IOCL Propel LLDPE 500M24A
IOCL Propel LLDPE 500M24A is a butene comonomer-based linear low-density polyethylene (LLDPE) manufactured by Indian Oil Corporation Ltd (IOCL) under its PROPEL polymer brand. It is produced using Nova Chemicals’ Sclairtech solution polymerization technology — a precision process that delivers a narrow molecular weight distribution, consistent melt behaviour and excellent flow properties. With a melt flow index of 50 g/10 min, 500M24A is one of the highest-flow LLDPE grades in IOCL’s portfolio, designed specifically for applications where fast mould filling, low warpage and good dispersion of pigments and additives are critical requirements.
IOCL describes 500M24A as a natural-coloured polymer with narrow molecular weight distribution, excellent processability and outstanding flow properties. Its linear polymer structure, derived from the LLDPE family, gives it better tensile strength, toughness and chemical resistance compared with LDPE grades of similar density — making it a preferred base resin for colour and additive masterbatches where the carrier polymer must disperse high loadings uniformly without compromising melt flow or the final product’s mechanical integrity.
According to IOCL’s product technical datasheet, LLDPE 500M24A is designed as a base resin for masterbatches and to make moulding of flat and large warpage-free products and lids. These two primary roles — masterbatch carrier and injection-moulded lid resin — both demand the same core attributes: very high flow for fast filling and dispersion, narrow molecular weight distribution for uniform melt behaviour, and adequate stiffness and toughness for the finished part or compound to hold its shape and performance through end-use.
Technical Insights
Resin Properties
- MFI: 50 g/10 min (ASTM D1238, 190 °C / 2.16 kg) — This exceptionally high melt flow index is the defining characteristic of 500M24A. At 50 MFI, the resin flows rapidly and evenly through hot-runner systems, multi-cavity moulds and mixing equipment, enabling fast injection cycles, complete cavity fill and thorough pigment dispersion in masterbatch compounding. It is the reason this grade is specified specifically for large, flat lids and high-loading masterbatch formulations where slower-flowing resins would result in incomplete fill or uneven dispersion.
- Density: 0.924 g/cm³ (ASTM D1505, 23 °C) — A medium-low density for LLDPE, this value reflects the butene comonomer content and places 500M24A in the flexible-to-semi-rigid range. It supports good toughness and elongation in moulded parts, balanced with the dimensional stability needed for flat, warp-resistant lids and covers.
Mechanical Properties
All values are typical figures from IOCL’s product technical datasheet, measured on injection-moulded specimens. They are not specification limits.- Tensile Yield Strength: 11–12 MPa (ASTM D638) — Two official TDS copies report slightly different typical values (11 MPa and 12 MPa respectively); both indicate adequate structural strength for lids, covers and moulded flat parts that are not subject to high sustained mechanical loads.
- Elongation at Break: >500% (ASTM D638) — Very high elongation before fracture confirms the grade’s toughness. In masterbatch applications, this ensures the carrier resin does not embrittle compounds, even at high filler loadings. For moulded lids, it means they can flex and absorb impact without cracking.
- Flexural Modulus: 300 MPa (ASTM D790) — Reflects the stiffness of a moulded part. At 300 MPa, 500M24A produces semi-rigid lids and flat parts with enough rigidity to hold their shape in service, without the brittleness of higher-modulus grades. This lower modulus compared to OPaL M2550 (400 MPa) also means slightly more flexibility, which can be advantageous for snap-fit lid applications.
Thermal and Environmental Properties
- Vicat Softening Point: 98 °C (ASTM D1525, 10 N) — The temperature at which the material begins to soften under load. At 98 °C, 500M24A moulded parts retain their shape well below typical sterilization or heat-filling temperatures and are suitable for most ambient and moderately warm storage and distribution environments.
- Environmental Stress Crack Resistance (ESCR), F50: <10 hours (ASTM D1693B) — A low ESCR value indicates limited resistance to cracking under sustained stress in the presence of aggressive chemicals. This is acceptable and expected for 500M24A, which is designed for masterbatch compounding and flat lids rather than pressure-rated pipes or chemical containers that require high ESCR. Specifying 500M24A for stress-crack-sensitive applications should be avoided.
Recommended Processing Window
IOCL recommends a processing temperature of 180–215 °C for injection moulding of LLDPE 500M24A. The high MFI means the resin flows easily within this window, enabling fast shot speeds and short fill times even for large, thin-section lids. Exceeding 215 °C risks oxidative degradation given the high surface area and low molecular weight of this high-flow grade — visible as colour change, odour development and loss of tensile properties. IOCL also advises processing the material within six months of delivery to maintain full performance.Applications of IOCL LLDPE 500M24A
Base Resin for Colour and Additive Masterbatches
The most widely cited application for IOCL LLDPE 500M24A is as a carrier or base resin in colour masterbatches, filler masterbatches and functional additive compounds. In masterbatch manufacturing, the carrier resin must have very high melt flow to allow thorough mixing of pigments, fillers and additives at high loading rates without causing excessive equipment wear or non-uniform dispersion. At 50 MFI, 500M24A provides the flow needed for twin-screw compounders and mixing extruders to blend high pigment concentrations — such as carbon black, titanium dioxide, organic pigments and inorganic fillers — into a homogeneous masterbatch that disperses cleanly when let down into final resin. Its narrow molecular weight distribution ensures consistent melt behaviour batch to batch, which is critical for masterbatch producers who need predictable processing and colour consistency across production runs.Injection-Moulded Lids, Covers and Flat Parts
500M24A is specifically designed by IOCL for injection moulding of flat and large warpage-free products and lids — a category that includes pail lids, drum covers, container caps, trays and other shallow mouldings where dimensional accuracy and flat surface finish are essential. Large flat injection mouldings are among the most demanding applications for any resin because differential cooling and uneven molecular orientation cause warpage — a chronic problem with lower-flow, broader-MWD grades. The 50 MFI and narrow molecular weight distribution of 500M24A allow very fast, even cavity fill with minimal frozen-in stresses, which directly reduces warpage and dimensional distortion after demoulding. The combination of adequate stiffness (300 MPa flexural modulus) and high elongation (>500%) ensures lids are rigid enough to seal containers properly while being tough enough not to crack on impact during handling or assembly.Filler Compounds and Polymer Blends
Beyond pure colour masterbatch, IOCL 500M24A is used in the broader filler compound and polymer blending sector — for example, as the polyethylene matrix or carrier in talc-filled compounds, calcium carbonate masterbatches and functional additive concentrates used in packaging, agriculture and industrial applications. The grade’s high flow reduces the viscosity of heavily filled compounds, improving their processability on single-screw extruders and injection moulding machines that would otherwise struggle with thick, high-viscosity blends. The food-contact approvals it carries (IS 10146, IS 10141 and FDA 177.1520) also make it suitable as a carrier in masterbatches intended for use in food-contact packaging resins, where the carrier resin’s regulatory status matters as much as its physical properties.Comparable Alternative 50 MFI LLDPE Injection Grades
IOCL 500M24A belongs to a small group of 50 MFI LLDPE injection grades available from Indian producers. These grades are routinely grouped together in distributor catalogues and are often evaluated side by side by masterbatch manufacturers and moulding processors. OPaL LLDPE M2550 from ONGC Petro Additions Ltd is the closest structural analogue to IOCL 500M24A in the Indian market. M2550 is a butene comonomer-based LLDPE produced via Ineos gas-phase polymerization technology with an MFI of 50.0 g/10 min and density of 0.934 g/cm³. OPaL explicitly recommends M2550 for masterbatch and compounding, housewares, thin-walled containers and lids, and notes it is “suitable for faster moulding cycle” — identical application positioning to IOCL 500M24A. Key differences: OPaL M2550 has a higher density (0.934 vs 0.924 g/cm³) and higher flexural modulus (400 MPa vs 300 MPa), which means M2550 produces stiffer moulded parts. Its Vicat softening point (95 °C) is marginally lower than 500M24A’s (98 °C). Both carry IS 10146, IS 10141 and FDA 177.1520 regulatory approvals. OPaL has not confirmed that M2550 is a drop-in replacement for IOCL 500M24A; equivalence is not confirmed by the manufacturer and should be validated through processing trials. Reliance Relene M26500 is a 50 MFI LLDPE injection grade from Reliance Industries Ltd with a density of 0.926 g/cm³, listed in Reliance’s LLDPE grade slate for lids, thin-walled injection mouldings and base resin for masterbatches — exactly the same use cases as IOCL 500M24A. Density (0.926 g/cm³) is very close to IOCL 500M24A (0.924 g/cm³). However, a full mechanical property comparison requires Reliance’s M26500 TDS, which is not available in the publicly published grade list alone. Reliance has not declared M26500 as interchangeable with 500M24A; equivalence is not confirmed by the manufacturer. GAIL G-Lene I26A500U is a 50 MFI LLDPE injection grade from GAIL (India) Ltd, listed by distributors as suitable for injection moulding applications requiring excellent gloss, high flow and a good balance of impact strength and rigidity. It is commonly offered alongside IOCL 500M24A, OPaL M2550 and Reliance M26500 in distributor product lines covering the LLDPE injection grade category. However, detailed density and mechanical property data from GAIL’s primary TDS for I26A500U were not available in the sources used for this page — making a full property comparison unverified. GAIL has not confirmed equivalence to 500M24A; equivalence is not confirmed by the manufacturer. The key differentiator for IOCL 500M24A in this peer group is its lower density (0.924 g/cm³) compared with M2550 and M26500, which contributes to a lower flexural modulus (300 MPa) and slightly more flexible finished parts. For applications where maximum rigidity is needed, OPaL M2550 may be the better fit. For applications where softer, more flexible lids or higher-toughness compounds are required, 500M24A’s lower density and modulus are advantages.Regulatory Compliance, Food Contact and Safety for IOCL LLDPE 500M24A
IOCL’s product technical datasheet for LLDPE 500M24A carries explicit regulatory approvals that are relevant for masterbatch producers and moulders supplying food-contact and drinking-water applications. The grade meets IS 10146:1982 — the Bureau of Indian Standards specification for polyethylene for safe use in contact with foodstuffs, pharmaceuticals and drinking water. It also conforms to the positive list of constituents as per IS 10141:1982, which specifies the additives and processing aids permitted in food-contact polyethylene. Additionally, IOCL confirms that the grade and its incorporated additives comply with FDA CFR Title 21, Section 177.1520 (Olefin Polymers) — the US FDA regulation for olefin-based polymers used in food-contact materials. These approvals are significant for masterbatch manufacturers who supply colour or additive concentrates to food-packaging producers. When 500M24A is used as the carrier resin, its regulatory clearances support the masterbatch supplier’s own compliance claims for food-contact applications, provided that the overall formulation (including pigments and additives) also meets the relevant standards.Manufacturer Details – IOCL PROPEL LLDPE 500M24A
IOCL Propel LLDPE 500M24A is manufactured by Indian Oil Corporation Ltd (IOCL), India’s largest public-sector oil and petrochemicals company. IOCL’s polymer portfolio is marketed under the PROPEL brand, covering polyethylene and polypropylene grades from its Panipat petrochemical complex. The LLDPE/HDPE swing plant at Panipat uses Nova Chemicals’ Sclairtech solution polymerization technology, which allows precise control of molecular weight distribution — the basis for 500M24A’s narrow MWD and highly consistent melt flow that distinguishes it from gas-phase LLDPE grades in processing predictability.Common Search Variants and Grade Misspellings

IOCL Propel PPRCP 2300MC
IOCL Propel PPRCP 2300MC is a polypropylene random copolymer (PPRCP) manufactured by Indian Oil Corporation Ltd (IOCL) under its PROPEL polymer brand. It is produced using Spheripol II Technology — a leading reactor polymerization process that incorporates the comonomer (typically ethylene) directly into the polypropylene chain in a random distribution during polymerization, rather than as a post-reaction blend. This reactor-grade approach gives 2300MC its defining characteristics: exceptionally good transparency, gloss, a well-balanced combination of stiffness and impact properties, and excellent organoleptic performance — meaning the resin imparts minimal taste, odour or extractable contamination to food or beverage contents in finished containers.
With a melt flow index of 30 g/10 min at 230 °C/2.16 kg, 2300MC is a high-flow PP random copolymer grade, designed for fast, efficient injection moulding of thin-wall parts and for injection stretch blow moulding (ISBM) of transparent bottles and containers. IOCL describes the grade in its PROPEL product line as a natural-coloured resin in prime/virgin quality, positioned specifically for houseware and consumer packaging applications where visual clarity and clean organoleptic performance are commercial requirements.
A polypropylene random copolymer is different from a PP homopolymer in a way that directly affects the properties relevant to transparent containers. In a homopolymer, propylene units pack into a highly ordered (isotactic) crystalline structure, which makes it stiff and strong but also opaque or hazy. In a random copolymer like 2300MC, a small amount of ethylene comonomer is distributed randomly along the PP chain. This disrupts regular crystallisation, producing smaller and more numerous crystallites — which scatter less light and give the resin its transparency and improved gloss. The random copolymer structure also softens the material slightly compared to homopolymer (lower melting point, better impact at lower temperatures), making it a more rounded material for everyday consumer product applications.
Technical Insights – Properties and What They Mean for Performance
Resin Properties
- MFI: 30 g/10 min (ASTM D1238, 230 °C / 2.16 kg) — A high melt flow index for a polypropylene grade. At 30 g/10 min, 2300MC flows rapidly through injection moulds, filling thin-wall sections completely and cleanly at high production speeds. This is the critical processing attribute for thin-wall injection moulded (TWIM) containers, where wall thicknesses of 0.5–1.5 mm must be filled reliably at short cycle times. High MFI also supports ISBM, where the preform must deform uniformly during blow moulding to produce consistent bottle wall thickness and optical clarity.
Mechanical Properties
- Tensile Yield Strength: 32 MPa (ASTM D638, 50 mm/min) — Good tensile performance at yield for a PP random copolymer. The lower tensile yield compared to PP homopolymer (typically 35–40 MPa) reflects the random copolymer’s slightly lower crystallinity, but 32 MPa is sufficient for rigid containers and housewares that must hold shape and resist deformation during filling, stacking and use.
- Elongation at Yield: 12% (ASTM D638, 50 mm/min) — Elongation at yield for a random copolymer is typically lower than for more flexible polyolefins. A 12% yield elongation indicates the material will deform in a controlled manner before yielding permanently — appropriate for rigid containers where some flex before permanent deformation is expected.
- Flexural Modulus: 1100 MPa (ASTM D790, 1.3 mm/min) — The primary measure of part stiffness. At 1100 MPa, 2300MC produces containers and housewares with good wall rigidity — the lids click shut positively, the container walls don’t flex under a firm grip, and the finished product has the premium feel associated with well-designed houseware products. This is lower than a PP homopolymer (typically 1400–1700 MPa), reflecting the softer random copolymer structure, but adequate for most rigid consumer container designs.
- Notched Izod Impact Strength: 50 J/m (ASTM D256, 23 °C) — Impact performance for a PP random copolymer at room temperature. At 50 J/m, 2300MC provides acceptable impact resistance for household containers, tubs and lids that may be dropped from handling height. This is significantly better than typical PP homopolymer at room temperature (often 20–30 J/m) — one of the practical advantages of the random copolymer structure. Applications requiring even higher impact performance, particularly at low temperatures, would be better served by a PP impact copolymer grade.
Thermal Properties
- Heat Deflection Temperature: 80 °C (ASTM D648, 0.46 N/mm²) — The temperature at which the material begins to deflect under load. An HDT of 80 °C means containers produced from 2300MC can withstand hot liquids and dishwasher lower rack temperatures without distorting. This is relevant for microwave-safe containers, hot-fill food packaging and kitchenware. However, for sustained high-temperature service above 80 °C, additional engineering assessment is needed.
- Vicat Softening Point: 125 °C (ASTM D1525, 10 N) — The point at which the surface begins to soften under needle pressure. At 125 °C, 2300MC provides thermal stability well above typical household use temperatures, confirming that the material is not at risk of surface softening or deformation under normal kitchen or houseware conditions.
Processing Temperature Window
IOCL recommends a processing temperature of 180–230 °C for PPRCP 2300MC on injection moulding and ISBM equipment. For thin-wall injection moulding, temperatures towards the upper end of this range (210–230 °C) combined with high injection speeds and pressures help achieve complete mould filling at minimum cycle time. For ISBM, preform temperature control is critical to achieving uniform wall distribution and consistent optical clarity in the finished bottle. Processing below 180 °C risks incomplete melt homogenisation, flow marks and poor weld line strength. Processing above 230 °C risks thermal degradation, discolouration and loss of organoleptic integrity — particularly important for food-contact grades.Applications of IOCL PPRCP 2300MC
Thin-Wall Injection Moulded Containers and Lids
The primary application for IOCL Propel PPRCP 2300MC is thin-wall injection moulding of transparent or translucent containers, lids and closures. The 30 g/10 min MFI allows the melt to flow rapidly through thin gates and wall sections at high injection speeds without incomplete fill, flow marks or weld line weakness — the common failure modes of low-flow resins in thin-wall moulds. The combination of 1100 MPa flexural modulus and 50 J/m notched Izod impact means the finished container has enough wall rigidity to feel solid and premium, while resisting the occasional drop or knock that consumer products routinely experience. Transparency and gloss — the defining optical properties of 2300MC — allow the consumer to see the contents clearly, which is a key purchase driver and quality signal for food containers, snack pots, salad bowls and similar products in retail settings.Rigid Housewares — Buckets, Tubs, Boxes and Storage Containers
IOCL lists rigid containers and housewares among the recommended applications for 2300MC, and the grade’s property balance suits a wide range of household injection moulded products beyond thin-wall packaging. For medium-wall buckets, storage tubs, utility boxes and food-grade containers, the random copolymer structure provides better clarity and lower haze than a standard PP homopolymer — allowing a semi-transparent or translucent appearance that lets users see contents without opening the lid. The flexural modulus of 1100 MPa provides adequate wall rigidity for stacking and filling, while the impact resistance of 50 J/m reduces cracking risk during normal household use. Excellent organoleptic properties — low odour and minimal flavour transfer — make 2300MC suitable for direct food contact housewares where taste integrity matters.Injection Stretch Blow Moulding (ISBM) — Bottles and Jars
Injection stretch blow moulding is a two-stage process where a polypropylene preform is injection moulded and then stretch blow moulded into a bottle or jar at elevated temperature. PP random copolymer grades like 2300MC are preferred for ISBM over homopolymers because the random comonomer distribution improves clarity in the blown article and softens the material enough to allow consistent stretch orientation across the bottle wall. The high MFI of 30 g/10 min supports efficient preform injection moulding at fast cycle times. The resulting bottle has the transparency associated with ISBM PP — approaching PET-like clarity for packaging of pharmaceuticals, food products, personal care items and household liquids where a clear rigid bottle is commercially preferred. For food and beverage ISBM applications, the food contact compliance of 2300MC is a direct qualification requirement.Comparable Alternative Grades for Transparent PP Injection Moulding
2300MC is positioned as a high-flow, transparent PP random copolymer for thin-wall and ISBM applications. Placing it in context with related grades helps buyers make informed decisions about which grade best matches their specific process and product requirements. IOCL Propel PPRCP 2120MC is another IOCL PP random copolymer grade from the same PROPEL range. Available technical references indicate 2120MC is positioned for similar injection moulding and houseware applications within the IOCL portfolio. The grade code suffix suggests a different MFI or property point compared to 2300MC — a lower flow suitable for slightly thicker-wall parts or where different mechanical performance trade-offs are needed. Without a directly accessible IOCL TDS for 2120MC in the same format, a numerical property comparison cannot be made with confidence. Buyers choosing between 2120MC and 2300MC should compare their respective TDS values and process the decision through mould trials, particularly if switching mid-production run. Equivalence between the two grades is not confirmed by IOCL documentation. IOCL Propel PPCP 3030MG is a polypropylene impact copolymer (PPCP) from IOCL — not a random copolymer. Impact copolymers are structurally different: they contain a rubber (elastomeric) dispersed phase that delivers significantly higher impact toughness, particularly at low temperatures, at the cost of optical clarity. 3030MG or similar impact copolymer grades from IOCL would be appropriate for applications where drop-impact performance is the priority and transparency is not required — crates, industrial containers, automotive parts. For transparent houseware containers and ISBM bottles where clarity is a commercial requirement, 3030MG and other impact copolymers are not suitable substitutes for 2300MC. PP random copolymer grades from Reliance Industries and other producers — Reliance produces PP copolymer grades under its own brand for injection moulding and ISBM applications. Other Indian producers of polypropylene, including HPL Additives’ downstream offerings, also market PP RCP grades for transparent container applications. Grades from any producer with MFI in the 25–35 g/10 min range and density near 0.900 g/cm³ (typical for PP RCP) would occupy a similar application space to 2300MC for thin-wall injection moulding and ISBM. However, no other producer has published documentation confirming their specific grade as a direct equivalent to IOCL 2300MC; MFI, mechanical properties, additive systems and organoleptic performance should be compared at the TDS level and validated through processing trials before substitution.Regulatory Compliance and Food Contact Approvals
IOCL’s product technical datasheet for PPRCP 2300MC confirms compliance with the relevant Indian and international food contact standards for polypropylene copolymers. For food contact use in India, polypropylene materials for articles intended to contact foodstuffs must meet IS 10910 (Specification for Polypropylene Materials for Use in Manufacture of Utensils and Articles Intended to Come into Contact with Foodstuff, Pharmaceuticals and Drinking Water — Copolymers). This standard sets requirements for PP copolymers specifically, distinguishing them from the homopolymer standard IS 10909. 2300MC’s compliance with this standard, as indicated in IOCL’s regulatory declarations, confirms its suitability as a food-contact material for the manufacture of food containers, storage boxes and kitchen utensils when processed and used within the conditions specified. 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 applications — a standard that applies to polypropylene resins and copolymers used in food packaging and storage articles. Excellent organoleptic properties — a specific positioning claim made by IOCL for 2300MC — means the resin is formulated to minimise taste, odour and extractable residue transfer to food or beverage contents. This is a direct commercial requirement for food-grade containers and bottles, where even mild taint or odour from the container material would be unacceptable to brand owners and consumers.Alternative Names, Common Search Variants and Grade Misspellings
