Products

IOCL Propel PPCP 3250MG is a polypropylene impact copolymer (PPCP) manufactured by Indian Oil Corporation Ltd (IOCL) under its PROPEL polymer brand. It is produced at IOCL’s Panipat Petrochemical Complex using Spheripol II Technology — an advanced loop-reactor polymerization process that builds a heterophasic polymer structure in-reactor rather than through post-reactor blending. IOCL classifies 3250MG as a high-flow, medium-impact-resistance grade, positioning it with good processability, good gloss and surface finish, and good substrate bonding — the combination of attributes that defines an effective extrusion coating and lamination resin. The term “heterophasic” describes the internal architecture of this polymer. Unlike a PP random copolymer where ethylene is distributed randomly along individual polymer chains, a heterophasic PP copolymer contains a dispersed elastomeric phase (ethylene-propylene rubber) embedded within a semi-crystalline polypropylene matrix — built as a single reactor product. This rubber phase is what delivers the improved impact resistance relative to PP homopolymer, while the PP matrix preserves stiffness, gloss and thermal stability. With an MFI of 25 g/10 min at 230 °C/2.16 kg, 3250MG flows readily at extrusion coating line speeds and in injection moulding cycles, making it a practical high-throughput resin for consumer-facing and industrial surface-critical applications. IOCL Propel PPCP 3250MG is designed for extrusion coating, lamination, appliance parts, housewares, and compounding. The grade’s combination of high flow, good adhesion on substrates, and gloss performance suits applications where the PP coating or moulded surface must meet both mechanical and aesthetic requirements. For extrusion coating on raffia fabric, paper or other substrates, 3250MG’s substrate bonding characteristic is the key functional attribute. For injection-moulded appliance parts and housewares, the balance between its 1200 MPa flexural modulus, 75 J/m impact resistance and 145 °C Vicat softening point positions it as a structurally capable resin that holds shape well under domestic and light-industrial service conditions.

Technical Insights

Resin Properties

• MFI: 25 g/10 min (ASTM D1238, 230 °C / 2.16 kg) — A high MFI for a polypropylene impact copolymer. At 25 g/10 min, 3250MG flows efficiently through extrusion coating dies and injection mould cavities at normal processing temperatures, allowing high line speeds in coating applications and short cycle times in injection moulding. This elevated flow is a deliberate design attribute — it ensures the molten polymer wets the substrate surface thoroughly during extrusion coating, which is directly linked to the adhesion and substrate bonding performance IOCL highlights for this grade.
• Density: 0.90 g/cm³ (ASTM D1505, 23 °C) — Standard density for a polypropylene copolymer, reflecting the combination of the semi-crystalline PP matrix and the lower-density elastomeric dispersed phase. At 0.90 g/cm³, 3250MG is lighter than polyethylene-based coating resins, which is a practical advantage in packaging and lamination where part weight and material cost per unit area are factors.

Mechanical Properties

• Tensile Yield Strength: 26 MPa (ASTM D638, 50 mm/min) — A moderate tensile yield, lower than PP random copolymer grades (typically 30–35 MPa) and PP homopolymer (35–40 MPa), which is expected for an impact copolymer where the dispersed rubber phase moderates matrix stiffness and yield behaviour. For extrusion-coated substrates and injection-moulded housewares, a 26 MPa tensile yield provides adequate structural performance under normal handling, filling and service loads.
• Elongation at Yield: 6% (ASTM D638, 50 mm/min) — Controlled deformation before permanent yield, consistent with a moderately stiff PP copolymer. The elongation at yield is relevant to coated substrate applications, where the coating layer must deform with the substrate under flexing or tension without de-bonding prematurely.
• Flexural Modulus: 1200 MPa (ASTM D790, 1.0% secant, 1.3 mm/min) — The primary measure of part and coating stiffness. At 1200 MPa, 3250MG is stiffer than IOCL’s PP random copolymer 2300MC (1100 MPa), reflecting the higher crystallinity retained in the PP matrix of the heterophasic structure. For appliance housings, houseware containers and laminated structures, this modulus provides good dimensional stability and a solid, premium feel in the finished part.
• Notched Izod Impact Strength: 75 J/m (ASTM D256, 23 °C) — Meaningfully higher impact toughness than PP random copolymers (typically 40–60 J/m) and substantially higher than PP homopolymer (typically 20–30 J/m). The 75 J/m notched Izod confirms that the heterophasic rubber phase is working effectively — absorbing impact energy and reducing crack propagation under sharp-notch conditions. For appliance parts that must survive assembly stresses and product lifetime impacts, and for housewares subject to everyday drops and knocks, this impact performance provides a practical safety margin.

Thermal Properties

• Heat Deflection Temperature: 100 °C (ASTM D648, 0.46 N/mm²) — Notably higher than IOCL’s random copolymer 2300MC (80 °C HDT), reflecting the higher crystallinity of the PP matrix in 3250MG’s heterophasic structure. A 100 °C HDT means moulded parts and coated substrates maintain dimensional stability and shape well above normal domestic use temperatures — including hot-liquid contact, dishwasher exposure and light industrial applications up to 90–95 °C.
• Vicat Softening Point: 145 °C (ASTM D1525, 10 N) — A high Vicat for a PP copolymer grade, again reflecting the well-crystallised PP matrix. At 145 °C, 3250MG’s surface remains firm under needle load well above any practical service temperature for houseware, appliance or laminated packaging applications, confirming good thermal robustness of the resin.

Processing Temperature Window

IOCL recommends a processing temperature of 170–230 °C for PPCP 3250MG, applicable to both extrusion coating lines and injection moulding. At the lower end (170–190 °C), the resin is appropriate for slower-speed injection moulding of thicker sections. For extrusion coating at commercial line speeds, melt temperatures towards 200–225 °C typically provide the best balance of flow, adhesion and surface quality. Exceeding 230 °C risks thermal degradation, colour change and potential gel formation; operating below 170 °C risks incomplete homogenisation and poor substrate wetting.  

Applications of IOCL PPCP 3250MG

Extrusion Coating on HDPE Raffia Fabric and Paper

IOCL Propel PPCP 3250MG is designed for extrusion coating on substrates such as HDPE raffia fabric and paper. In this application, a thin layer of molten 3250MG is deposited onto the moving substrate via a flat die extrusion line, bonding to the surface on contact and cooling to form an integrated coated structure. The high MFI of 25 g/10 min allows the resin to spread uniformly at extrusion coating line speeds, while the good substrate bonding characteristic noted by IOCL ensures reliable adhesion between the PP coating layer and the substrate without the delamination risk that would occur with a grade not formulated for this application. For HDPE raffia, the coated structure is used in woven sacks, tarpaulins and FIBC liners where the PP coating adds printability, barrier properties and sealing capability. For paper, the PP extrusion coating layer creates heat-sealable, moisture-resistant food-service packaging and industrial wrapping materials.

Lamination and Composite Structures

3250MG is listed by IOCL among the recommended applications for lamination — processes where PP film or coatings are bonded to paper, film, foil or fabric substrates under heat and pressure to create multi-layer composite structures. The grade’s good gloss and surface finish properties ensure that PP laminate layers present a smooth, aesthetically consistent surface, which matters for printed retail packaging and consumer-facing laminated products. The combination of 1200 MPa stiffness and good bonding ensures the laminated structure maintains cohesion under the mechanical stresses of die-cutting, folding, filling and distribution.

Appliance Parts and Industrial Components

The elevated thermal performance of 3250MG — HDT 100 °C and Vicat 145 °C — makes it well-suited for injection-moulded housings, covers and structural components in domestic and light-commercial appliances. Appliance parts that sit near heat sources, are exposed to hot air, or contact warm liquids require materials that maintain dimensional stability beyond 60–80 °C. At 100 °C HDT, 3250MG is a practical choice for components such as appliance back panels, air vent housings, motor covers and utility parts where standard PP random copolymer grades (typically 75–85 °C HDT) may not provide sufficient thermal margin. The 75 J/m impact resistance additionally provides protection against mechanical stresses during assembly and product service.

Housewares and Consumer Containers

IOCL explicitly recommends 3250MG for housewares, and its property balance — good surface finish, 1200 MPa stiffness, 75 J/m impact, and elevated thermal resistance — suits a range of moulded household products including storage containers, utility boxes, trays, organisers and kitchen items where PP’s chemical resistance, cleanability and light weight are advantages. The good gloss and surface finish properties specified by IOCL mean 3250MG-based houseware products have an attractive surface appearance directly from the mould, reducing the need for secondary finishing operations. For applications requiring contact with food or beverages, regulatory compliance (see below) should be confirmed for the specific article and use conditions.

Compounding Base Resin

IOCL also lists compounding among the recommended uses for 3250MG. In this role, the grade serves as a PP impact copolymer base resin into which fillers, pigments, flame retardants, glass fibre or other functional additives are incorporated to produce PP compounds with tailored property profiles. The high MFI of the base resin facilitates mixing and dispersive compounding at commercial throughputs, and the heterophasic structure provides a starting impact toughness that can be further enhanced or balanced against filler loading through the compounding formulation.

Comparable Alternative Grades for PP Extrusion Coating and Impact Copolymer Applications

3250MG occupies a specific position in IOCL’s PP grade portfolio: a high-flow PPCP tuned for extrusion coating and surface-critical applications, with medium impact resistance and elevated thermal stability. Understanding how it relates to nearby grades helps processors select the most appropriate resin for their process and end-product requirements. IOCL Propel PPCP 3250MN is another IOCL PP impact copolymer grade with a similar grade designation. Available sources indicate 3250MN is positioned primarily for injection moulding rather than extrusion coating. The “MN” suffix versus “MG” suffix in IOCL’s grade nomenclature may reflect different additive packages, flow characteristics or processing optimisation between the two grades. Without a directly accessible TDS for 3250MN in the same format, a full numerical comparison of MFI, tensile, impact and thermal values is not possible here. Processors evaluating 3250MN as an alternative to 3250MG for extrusion coating should verify MFI, neck-in behaviour and substrate bonding performance through processing trials. Equivalence is not confirmed by IOCL documentation. IOCL Propel PPCP 3120MA is another impact copolymer grade in IOCL’s PROPEL PP range, listed in commercial sources for injection moulding applications. Its grade code suggests a different MFI and application tuning compared to 3250MG. For extrusion coating where high flow and specific substrate bonding are required, 3120MA’s processing suitability would need to be verified against its own TDS data. It is not confirmed by IOCL as a direct substitute for 3250MG. IOCL Propel PPRCP 2300MC is IOCL’s PP random copolymer grade (reviewed separately), with MFI 30 g/10 min, flexural modulus 1100 MPa, and Vicat 125 °C. Compared to 3250MG: 2300MC has a slightly higher MFI but lower thermal performance (HDT 80 °C vs 100 °C, Vicat 125 °C vs 145 °C) and lower impact resistance (50 J/m vs 75 J/m). Random copolymer 2300MC is the better grade for applications requiring transparency and organoleptic performance (e.g., food containers and ISBM bottles). 3250MG is the better grade for applications requiring higher thermal performance, better impact toughness, and good substrate bonding in extrusion coating — where the slight opacity of the heterophasic structure is not a commercial limitation. PP impact copolymer extrusion coating grades from other Indian producers — OPaL, Reliance Industries and GAIL produce PP copolymer grades for extrusion coating and lamination applications. A PP impact copolymer grade from any of these producers with MFI in the 20–30 g/10 min range would occupy a similar processing and application space to 3250MG. No producer has published documentation confirming a specific alternative grade as equivalent to IOCL 3250MG; each candidate grade’s TDS should be compared at the property level, and processing trials should be conducted before substitution in a qualified production line.

Regulatory Compliance and Food Contact Information

IOCL’s product technical datasheet for PPCP 3250MG confirms the grade’s compliance with relevant Indian and international standards for PP-based materials intended for food and pharmaceutical contact applications. For contact with foodstuffs, pharmaceuticals and drinking water in India, polypropylene copolymer materials are governed by IS 10910 (Specification for Polypropylene Copolymers for Use in Manufacture of Utensils and Articles Intended to Come into Contact with Foodstuff, Pharmaceuticals and Drinking Water). 3250MG’s datasheet confirms compliance with this standard, establishing its suitability as a material for producing food-contact articles when processed and used within the conditions specified by the standard. The grade and its incorporated additives also comply with FDA CFR Title 21, Section 177.1520 (Olefin Polymers), the US FDA regulation governing olefin-based polymers in food-contact articles, including polypropylene homopolymers and copolymers. For final regulatory qualification of specific food-contact articles produced from 3250MG, processors and brand owners are responsible for confirming compliance of the finished article — including processing conditions, pigments, additives, and intended use conditions — with the requirements of IS 10910 and any other applicable regulations.

Alternative Names, Common Search Variants and Grade Misspellings

IOCL Propel PPCP 3250MG is also commonly searched and referenced as: PROPEL PP 3250MG, IOCL 3250MG extrusion coating granules, PP CP 3250MG, PP impact copolymer 3250MG, IOCL PPCP 3250MG, PP copolymer 3250MG IOCL, PP-CP extrusion coating IOCL 3250MG, and Propel 3250MG polypropylene granules. Frequent misspellings and alternate spellings include: 3250 MG, 3250-MG, 3250mg iocl, PPCP 3250mg propel, PP copolymer IOCL 3250 MG, and 3250Mg IOCL extrusion.

IOCL PPCP Propel 3250MN is a polypropylene impact copolymer (PPCP) manufactured by Indian Oil Corporation Ltd (IOCL) under its PROPEL polymer brand at the Panipat Petrochemical Complex, produced using Spheripol II Technology. IOCL classifies 3250MN as a heterophasic, natural-coloured, high-flow, medium-impact-resistance grade with good processability, good surface finish and gloss, and an optimised balance of stiffness and toughness — positioning language that defines it squarely as a workhorse injection moulding resin for consumer and industrial applications. The grade’s MFI of 25 g/10 min at 230 °C / 2.16 kg places it in the high-flow segment of injection moulding PP impact copolymers. High flow supports fast cavity filling, shorter injection cycle times and reliable filling of complex or multi-cavity moulds without excessive injection pressure. The heterophasic structure — a dispersed elastomeric phase within a semi-crystalline PP matrix, built in-reactor via Spheripol II — delivers impact resistance of 80 J/m notched Izod, meaningfully higher than both PP homopolymer (typically 20–30 J/m) and PP random copolymer grades (typically 40–60 J/m). The result is a resin that combines the processing efficiency of a high-flow PP with the toughness margin needed for parts that must resist handling, assembly and service impacts.

Technical Insights

Resin Properties

• MFI: 25 g/10 min (ASTM D1238, 230 °C / 2.16 kg) — A high-flow MFI for an injection moulding PP impact copolymer. At 25 g/10 min, 3250MN fills mould cavities efficiently at normal injection pressures and temperatures, allowing good cycle times across a wide range of part geometries — from medium-wall housewares and appliance housings to rigid packaging containers. This MFI is significantly higher than standard injection moulding PP impact grades (often 8–15 MFI) used for thicker-wall parts, making 3250MN well-suited to faster production rates without the processing challenges of very high-flow grades at 50+ MFI.
• Density: 0.90 g/cm³ (ASTM D1505, 23 °C) — Standard PP impact copolymer density, reflecting the PP matrix with dispersed rubber phase. Parts moulded from 3250MN are light relative to engineering polymers, which is a practical advantage for housewares, appliance housings and packaging components where part weight contributes to consumer cost and logistics efficiency.

Mechanical Properties

• Tensile Yield Strength: 26 MPa (ASTM D638, 50 mm/min) — Adequate tensile performance for the structural requirements of injection-moulded appliance housings, houseware containers and rigid packaging, where parts must resist deformation under fill weight, stacking loads and handling stresses without permanent yield.
• Elongation at Yield: 8% (ASTM D638, 50 mm/min) — Higher than IOCL’s higher-flow injection moulding PPCP grades (3550MN at 5%, 3250MG at 6%), reflecting the slightly more compliant character of 3250MN’s impact copolymer structure at this flow level. Higher elongation at yield indicates that the material accommodates more deformation before permanent change — relevant for parts assembled with snap-fit connections or exposed to bending loads.
• Flexural Modulus: 1200 MPa (ASTM D790, 1.0% secant, 1.3 mm/min) — The wall stiffness of moulded parts from 3250MN is equivalent to IOCL’s 3250MG and 3550MN at the same 1200 MPa modulus. This means lids sit flat, container walls resist flex under hand pressure, and appliance panels hold dimensional tolerances across their service life — the “premium feel” associated with well-specified PP copolymer housewares and appliance parts.
• Notched Izod Impact Strength: 80 J/m (ASTM D256, 23 °C) — The best notched Izod impact performance among IOCL’s injection moulding-oriented PPCP grades documented in this series. At 80 J/m, 3250MN provides a meaningful toughness advantage over 3250MG (75 J/m) and 3550MN (65 J/m). For appliance parts that must survive assembly processes, occasional drops and mechanical loads during service, and for rigid packaging containers that must withstand distribution handling without cracking, this impact toughness directly reduces field failure risk.

Thermal Properties

• Heat Deflection Temperature: 110 °C (ASTM D648, 0.46 N/mm²) — The highest HDT in IOCL’s injection moulding PPCP range documented in this series. At 110 °C, moulded parts maintain structural integrity and dimensional stability under load well beyond the 80–90 °C operating environments typical of domestic appliances, hot-air environments and proximity to heating elements. This 10 °C advantage over 3250MG (100 °C) and 5 °C advantage over 3550MN (105 °C) reflects the thermally optimised character of 3250MN for its injection moulding target applications.
• Vicat Softening Point: 150 °C (ASTM D1525, 10 N) — The highest Vicat among IOCL’s injection moulding PPCP grades in this series, tied only with 4015EG. At 150 °C Vicat, the resin surface remains firm under needle load well above any practical service temperature for injection-moulded housewares, appliance components and automotive trim. This confirms strong underlying PP matrix crystallinity despite the impact-enhancing rubber phase.

Processing Temperature Window

IOCL recommends a processing temperature of 170–230 °C for PPCP 3250MN on injection moulding equipment. For standard housewares and appliance parts at normal wall thicknesses, melt temperatures in the 190–215 °C range are typical. For parts with longer flow paths or thinner sections where full cavity fill requires more flow, temperatures towards 215–225 °C may be used within the stated window. Processing below 170 °C risks incomplete melt homogenisation and poor surface quality. Processing above 230 °C risks thermal degradation and loss of the gloss and surface finish properties that IOCL highlights as key attributes of this grade.

Applications of IOCL PPCP 3250MN

Electrical Appliance Parts and Housings

IOCL lists electrical appliance parts as the first recommended application for 3250MN. Appliance components — outer housings, fan covers, control panel bases, motor brackets, vents and internal structural elements — require a combination of properties that 3250MN is specifically designed to deliver: good surface quality and gloss for visible panels and housings, 1200 MPa flexural modulus for dimensional stability and structural rigidity, 80 J/m impact resistance to survive assembly stresses and product lifetime use, and the highest HDT (110 °C) in IOCL’s injection moulding PPCP range to handle the thermal environment near motors, heating elements and compressors. The high-flow MFI of 25 g/10 min supports fast production cycles and consistent surface finish across high-volume appliance part runs.

Housewares and Consumer Storage Products

For household injection-moulded products — storage boxes, organisers, containers, utility items, trays and lids — 3250MN’s combination of good gloss, 80 J/m toughness and 1200 MPa stiffness creates a finished product with the surface quality and structural feel that consumers associate with premium housewares. At MFI 25, the resin fills standard houseware moulds reliably without needing extreme injection conditions, and the 110 °C HDT means moulded parts do not warp or distort under hot-storage conditions, dishwasher exposure or contact with warm contents. For houseware applications with food or beverage contact, the grade’s compliance with IS 10910 and FDA CFR 21, 177.1520 (see regulatory section) supports food-contact article production.

Automotive Components and Interior Trim

IOCL recommends 3250MN for automotive components — a broad category that in injection moulding includes interior trim panels, pillar covers, seat components, dashboard sub-assemblies, glove box bodies and door pocket inserts. Automotive interior injection moulding requires PP resins that combine good flow for filling complex cavity geometries, sufficient impact resistance to pass assembly and quality control impact tests, and adequate thermal stability for sustained in-car temperatures that can reach 80–100 °C on hot summer days in Indian conditions. 3250MN’s 110 °C HDT exceeds the typical automotive interior thermal requirement, and its 80 J/m impact provides the toughness needed for parts that must survive both assembly operations and long-term in-vehicle use. High flow at MFI 25 supports the injection of large, thin-section automotive trim parts with consistent surface finish.

Rigid Packaging

IOCL lists rigid packaging among the recommended applications for 3250MN. In this segment, the grade is applicable to injection-moulded rigid containers, closures, caps, jars and packaging trays where the combination of good gloss, food-contact compliance, adequate toughness and fast cycle processing makes PP impact copolymer a commercially practical choice over heavier or more expensive materials. The 80 J/m notched Izod ensures containers and closures resist cracking under the fill, closure and distribution stresses of rigid packaging supply chains, while the high-flow MFI supports the fast cycle times needed for high-volume packaging production.

Comparable Alternative Grades for PP Impact Copolymer Injection Moulding in India

3250MN sits at a well-defined point in IOCL’s injection moulding PPCP range: MFI 25, medium-high impact, and the best thermal performance among the standard-flow injection moulding PPCP grades in the PROPEL line. IOCL PPCP Propel 3550MN is the directly comparable higher-flow injection moulding PPCP grade, reviewed separately in this series. At MFI 55, 3550MN is designed for thin-wall and very high-speed injection moulding where maximum flow is the priority. The trade-off is slightly lower impact (65 J/m vs 80 J/m), lower HDT (105 °C vs 110 °C) and lower Vicat (145 °C vs 150 °C). For applications where standard cycle times and moderate-wall part geometries are acceptable, 3250MN’s better thermal and impact performance makes it the stronger material choice. For ultra-thin-wall parts or maximum throughput applications, 3550MN’s higher flow is the priority driver and 3250MN may not fill the mould adequately without process changes. IOCL PPCP Propel 3650MN appears in IOCL’s grade documentation alongside 3250MN and 3550MN within the nucleated injection moulding PPCP family. The grade code suggests 3650MN represents a different (likely higher) flow point in the same family. Without a full accessible TDS for 3650MN, a numerical property comparison is not possible here. Processors requiring flow above MFI 25 and below MFI 55 should investigate 3650MN as a potential intermediate grade, subject to IOCL’s official documentation and processing trials. Equivalence to 3250MN is not confirmed. IOCL PPCP Propel 3250MG is the extrusion coating-oriented grade with the same MFI of 25 g/10 min (reviewed separately). Despite sharing the same flow rate, 3250MG is formulated for substrate bonding and low neck-in in extrusion coating applications — a different additive system and performance focus from 3250MN, which is injection moulding-specific. The two grades are not interchangeable; 3250MN should be used for injection moulding and 3250MG for extrusion coating and lamination. IOCL PPCP Propel 5080MG is a super-impact copolymer grade with a much larger rubber phase delivering very high toughness — well above the 80 J/m of 3250MN. 5080MG is positioned for applications where maximum impact is the overriding requirement (heavy-duty crates, containers, automotive bumpers). Its higher rubber content typically means lower stiffness and lower flow compared to 3250MN. It is not a substitute for 3250MN in appliance, houseware or rigid packaging applications. PP impact copolymer injection moulding grades from other Indian producers — OPaL, Reliance Industries and GAIL produce PP impact copolymer grades for injection moulding. A grade with MFI in the 20–30 g/10 min range and notched Izod above 70 J/m from any of these producers would occupy a comparable application space to 3250MN. No specific grade from another producer has been confirmed as equivalent to IOCL 3250MN; TDS comparison and processing trials are required before substitution.

Regulatory Compliance and Food Contact Information

IOCL’s product technical datasheet for PPCP 3250MN confirms compliance with the relevant Indian and international standards for polypropylene copolymer materials in food and pharmaceutical contact applications. The grade meets IS 10910 (Specification for Polypropylene Copolymers for Use in Manufacture of Utensils and Articles Intended to Come into Contact with Foodstuff, Pharmaceuticals and Drinking Water) — the BIS standard governing PP copolymers in food-contact applications, distinct from IS 10909, which applies to PP homopolymers. IS 10910 compliance establishes 3250MN as a suitable material for food-contact injection-moulded articles, including containers, trays, lids and rigid packaging when processed and used within the conditions of the standard. The grade and its incorporated additives also comply with FDA CFR Title 21, Section 177.1520 (Olefin Polymers) — the US FDA regulation for olefin-based polymers in food-contact applications. For processors manufacturing food-contact rigid packaging, houseware containers or food-service components from 3250MN, final regulatory qualification of the finished article — including any colorants, additional additives and end-use conditions — remains the responsibility of the processor and brand owner.

Alternative Names, Common Search Variants and Grade Misspellings

IOCL PPCP Propel 3250MN is also commonly searched and referenced as: PROPEL PP 3250MN, IOCL 3250MN injection moulding granules, PP impact copolymer 3250MN, PP CP 3250MN, PPCP 3250MN IOCL, high-flow PP copolymer 3250MN, IOCL 3250MN appliance grade, and Propel 3250MN PP granules 25 kg. Frequent misspellings and alternate spellings include: 3250 MN, 3250-MN, 3250mn iocl, 3250mg propel, PPCP 3250 MN, PP impact IOCL 3250MN, and propel pp 3250-mn injection.

IOCL PPCP Propel 4015EG is a polypropylene impact copolymer (PPCP) manufactured by Indian Oil Corporation Ltd (IOCL) under its PROPEL polymer brand, produced using Spheripol II Technology. IOCL positions 4015EG as a high-impact-resistance, nucleated, heterophasic grade with medium flow for easy processing — a property combination that places it in a fundamentally different segment from IOCL’s high-flow injection moulding PP grades. Where grades like 3550MN (MFI 55) and 3250MG (MFI 25) are designed for fast injection moulding at high shear, 4015EG is designed for the lower-shear, higher-viscosity processing conditions of blow moulding and sheet extrusion. At an MFI of 1.6 g/10 min (230 °C / 2.16 kg), 4015EG is a low-flow grade by PP standards. This is intentional and necessary. In blow moulding, the molten polymer must form a stable, uniform parison (or preform in injection stretch blow moulding) that holds its shape under gravity between extrusion and inflation — a task that requires adequate melt strength and viscosity rather than fast flow. In sheet extrusion, the melt must exit the flat die and solidify into a dimensionally stable sheet without excessive sag, sagging being the primary quality failure of low-viscosity resins on sheet lines. The 1.6 MFI of 4015EG provides the melt strength needed for both of these processes. The notched Izod impact strength of 200 J/m at 23 °C is the defining mechanical attribute of this grade. This is exceptionally high for a PP copolymer — approximately three times the impact toughness of IOCL’s injection moulding PPCP grades (3250MG and 3550MN at 75 J/m and 65 J/m respectively) and far above any PP homopolymer or random copolymer. The large dispersed rubber phase responsible for this toughness is built into the polymer architecture during Spheripol II reactor polymerisation, not blended in post-reactor — delivering uniform distribution of the impact modifier throughout the resin.

Why 4015EG Is Specified for Blow Moulding and Sheet Extrusion

The combination of low MFI and very high impact toughness in 4015EG directly reflects the design requirements of blow moulding and sheet extrusion applications. Blow-moulded PP bottles, automotive ducts and hollow components must survive drop impacts and mechanical loads in service. Extruded PP sheets destined for thermoforming must withstand the forming forces applied during vacuum or pressure thermoforming without cracking at tool contact points. Thermoformed automotive parts, industrial trays and large containers must resist impact across their service life. The 200 J/m notched Izod of 4015EG ensures that moulded and formed articles from this resin are tough enough for these demanding end uses.

Technical Insights

Resin Properties

• MFI: 1.6 g/10 min (ASTM D1238, 230 °C / 2.16 kg) — Low by PP standards, and deliberately so. Blow moulding and sheet extrusion require a higher-viscosity melt than injection moulding. In extrusion blow moulding, the parison extruded from the die head must remain dimensionally stable for long enough to be enclosed by the mould and inflated — a low-viscosity (high-MFI) melt would sag, thin out and produce uneven wall distribution. In sheet extrusion, a low-viscosity melt would sag between the die and the calendar rolls, creating thickness variation. At 1.6 MFI, 4015EG provides the melt strength needed for parison stability and sheet gauge consistency.
• Density: 0.90 g/cm³ (ASTM D1505, 23 °C) — Standard for a PP impact copolymer. At 0.90 g/cm³, 4015EG produces light-weight moulded and sheet articles consistent with PP’s advantage over heavier engineering polymers and polyolefins.

Mechanical Properties

• Tensile Yield Strength: 27 MPa (ASTM D638, 50 mm/min) — Adequate tensile resistance for blow-moulded containers and thermoformed parts that must hold shape under the loads of filling, stacking and handling. At 27 MPa, 4015EG sits between rigid PP homopolymers and more compliant rubber-toughened grades, providing practical structural performance for its target applications.
• Elongation at Yield: 13% (ASTM D638, 50 mm/min) — Higher yield elongation than IOCL’s injection moulding PPCP grades (5–6%), reflecting the more compliant character of 4015EG’s large-rubber-phase heterophasic structure. Higher elongation at yield contributes to the material’s ability to deform substantially before yielding permanently — relevant to thermoforming, where the sheet must stretch and draw without early cracking at forming tool contact points.
• Flexural Modulus: 1150 MPa (ASTM D790, 1.3 mm/min) — Slightly lower than IOCL’s injection moulding PPCP grades (1200 MPa for 3250MG and 3550MN), reflecting the trade-off between impact toughness and stiffness inherent in high-impact heterophasic PP grades. At 1150 MPa, 4015EG maintains adequate wall rigidity for blow-moulded bottles, automotive components and thermoformed trays, while the large rubber phase delivers the toughness that defines this grade.
• Notched Izod Impact Strength: 200 J/m (ASTM D256, 23 °C) — Exceptional toughness. A notched Izod of 200 J/m is more than double that of most PP impact copolymers used for injection moulding (typically 65–100 J/m). This level of impact resistance positions 4015EG clearly as a high-impact grade rather than a medium-impact grade — suitable for applications where the moulded or thermoformed part must survive repeated mechanical impacts, drop loads, or assembly stresses without fracturing. For automotive ducts and panels that must pass drop-test specifications, and for PP blow-moulded containers that must withstand cold-chain and distribution handling, this toughness is the primary selection driver.

Thermal Properties

• Heat Deflection Temperature: 85 °C (ASTM D648, 0.46 N/mm²) — Lower than IOCL’s higher-crystallinity injection moulding PPCP grades (100–105 °C HDT), which is the expected consequence of the large rubber phase reducing effective matrix crystallinity. At 85 °C HDT, 4015EG moulded and thermoformed articles maintain shape under load up to temperatures consistent with outdoor storage, hot-fill packaging and automotive interior ambient conditions. Applications requiring sustained structural performance above 85 °C under load should be evaluated with this figure in view.
• Vicat Softening Point: 150 °C (ASTM D1525, 10 N) — The highest Vicat among IOCL’s PPCP grades documented in this series, confirming that the PP matrix component of 4015EG is well-crystallised with a high softening resistance despite the large rubber phase. At 150 °C Vicat, the resin surface remains firm under needle load well above any practical service temperature for blow-moulded bottles, automotive components and thermoformed industrial parts.

Processing Guidance

4015EG is designed for extrusion blow moulding and sheet extrusion — both continuous-extrusion processes rather than cyclic injection processes. IOCL’s full processing temperature recommendations for 4015EG were not fully accessible in public sources reviewed for this page; processors should refer directly to IOCL’s product technical datasheet for the specific barrel, die and melt temperature settings recommended for this grade on blow moulding and sheet extrusion lines. For general reference, PP impact copolymers at this MFI level are typically processed in the 190–240 °C melt temperature range on blow moulding equipment, but this is industry context rather than a confirmed IOCL recommendation for 4015EG specifically.

Applications of IOCL PPCP Propel 4015EG

Extrusion Blow Moulding – PP Bottles, Containers and Hollow Parts

Extrusion blow moulding of polypropylene requires a resin with sufficient melt viscosity to form a dimensionally stable parison and enough impact toughness in the finished part to survive filling, capping, labelling, distribution and consumer use. IOCL PPCP Propel 4015EG is specifically recommended for blow moulding applications, and its property profile — MFI 1.6 g/10 min for parison stability and 200 J/m notched Izod for part toughness — directly addresses both requirements. Blow-moulded PP bottles produced from 4015EG are used for packaging food products, household chemicals, personal care items and industrial fluids where PP’s chemical resistance, light weight and rigid structure are commercially preferred. For cold-chain or distribution-intensive applications where bottles must survive drop and impact loads, the high toughness of 4015EG provides a meaningful safety margin over lower-impact PP grades.

Sheet Extrusion and Thermoforming

PP sheet extrusion followed by thermoforming is used to produce trays, tubs, lids, industrial containers, automotive interior parts and large structural components. In this two-stage process, 4015EG granules are first extruded through a flat sheet die and solidified into uniform sheets, which are then reheated and formed into three-dimensional shapes using vacuum, pressure or matched-die thermoforming tools. The low MFI of 1.6 g/10 min ensures the extruded sheet has adequate melt strength to maintain gauge uniformity across the full sheet width, while the 13% elongation at yield and 200 J/m impact toughness allow the sheet to stretch and draw into deep thermoformed geometries without premature cracking at tool radii or corners. Thermoformed 4015EG parts in automotive and industrial applications benefit from the same toughness that makes the grade valuable for blow-moulded containers — resistance to crack propagation under mechanical load in service.

Automotive Components – Ducts, Panels and Structural Parts

IOCL lists automotive components among the recommended applications for 4015EG. In automotive manufacturing, PP impact copolymers are widely used for injection-moulded and blow-moulded interior trim, underbody ducts, air ducting systems, door skins and boot liners where toughness, light weight and chemical resistance are required. The 200 J/m notched Izod of 4015EG is directly relevant to automotive specifications that require moulded parts to survive defined drop or pendulum impact tests at ambient and sub-ambient temperatures. For blow-moulded automotive ducts and hollow structural components where extrusion blow moulding is the preferred process, 4015EG’s combination of low MFI and high impact makes it a technically appropriate base resin. For thermoformed automotive interior panels and protective covers, the sheet extrusion and forming capability of the grade enables large-format parts production that would not be practical by injection moulding.

Comparable Alternative Grades for High-Impact PP Blow Moulding and Sheet Extrusion in India

4015EG occupies a specific and relatively specialised position in IOCL’s PP portfolio: a low-MFI, high-impact PPCP grade designed for blow moulding and sheet extrusion. Most of IOCL’s PPCP grades documented in publicly accessible sources are injection moulding grades with MFI in the 10–55 g/10 min range — making direct numerical comparisons within the IOCL range informative for understanding what makes 4015EG distinctive. IOCL PPCP Propel 3550MN and 3250MG are the injection moulding and extrusion coating-oriented PPCP grades reviewed earlier in this series. Their MFI values (55 and 25 g/10 min respectively) are fundamentally incompatible with blow moulding or sheet extrusion at commercial standards: the melt is too fluid to form a stable parison in blow moulding and would sag excessively in sheet extrusion. These grades are not alternatives to 4015EG for its intended applications and should not be evaluated as such. IOCL PPCP Propel 4100MH is another IOCL impact copolymer grade with an MFI reported in the 11 g/10 min range. At 11 MFI, 4100MH would be better suited to injection moulding of larger or thicker-wall parts rather than to blow moulding or sheet extrusion, where 1.6 MFI is appropriate. Without a directly accessible TDS for 4100MH showing notched Izod impact values comparable to 4015EG, a full property comparison is not possible here. IOCL has not confirmed 4100MH as an equivalent to 4015EG; their different MFI profiles suggest different process and application targets. IOCL PPCP Propel 3030MG is another IOCL impact copolymer listed in commercial sources for injection moulding applications. Its application positioning is for injection moulded parts rather than blow moulding or sheet, and its flow characteristics would be different from the 1.6 MFI required for 4015EG’s applications. It is not a substitute for 4015EG. PP impact copolymer blow moulding grades from other Indian producers — OPaL, Reliance Industries and other domestic PP producers offer impact copolymer grades across a range of MFI values, including grades tuned for blow moulding and sheet extrusion. A PP impact copolymer from any producer with MFI in the 1–3 g/10 min range and high notched Izod impact (150 J/m or above) would occupy a similar processing space to 4015EG for blow moulding and thermoforming applications. No other producer has confirmed a specific grade as equivalent to IOCL 4015EG; TDS comparison and processing trials are required before substitution.

Regulatory Compliance and Food Contact Information

IOCL’s PPCP grades are produced with additive systems that meet relevant Indian and international standards for polypropylene contact with food and pharmaceuticals, and 4015EG is listed in the IOCL PROPEL range with similar compliance positioning to other grades in the portfolio. For food-contact articles produced by blow moulding or thermoforming from polypropylene copolymers in India, IS 10910 (Specification for Polypropylene Copolymers for Use in Manufacture of Utensils and Articles Intended to Come into Contact with Foodstuff, Pharmaceuticals and Drinking Water) is the relevant standard. For blow-moulded PP bottles intended for food or beverage packaging, and for thermoformed food trays, compliance with IS 10910 is a material qualification requirement. The grade is also positioned for compliance with FDA CFR Title 21, Section 177.1520 (Olefin Polymers), applicable to PP-based food-contact articles under US FDA regulations. Processors manufacturing food-contact articles from 4015EG should confirm compliance of their specific article — including any pigments, additives and processing aids — with IS 10910 and other applicable regulations. IOCL’s full regulatory statements for 4015EG should be verified against the official product technical datasheet.
