Understanding the Key Properties of HDPE 003F46

• Melt Flow Index — 0.30–0.35 g/10 min (ASTM D1238, 190 °C / 2.16 kg): A small but notable discrepancy exists between sources: IOCL’s own TDS reports MFI 0.30 g/10 min, while distributor documentation consistently cites 0.35 g/10 min. Both figures are typical values — not specification limits — and the difference is within the batch-to-batch variability expected for HDPE resins. The practical implication for blown film converters is the same in either case: an MFI in the 0.30–0.35 g/10 min range places 003F46 in the moderate-viscosity segment for HDPE film grades, providing enough melt strength to hold a stable bubble at standard blow-up ratios without excessive extruder back-pressure. Unlike the very low-MFI blow-moulding grades (such as HDPE 002DB52 at 0.2 g/10 min at 5 kg load), the film-grade MFI is measured at 2.16 kg and reflects extrusion film die conditions rather than parison behaviour.
• Density — 0.946 g/cm³ (ASTM D1505, 23 °C): At 0.946 g/cm³, HDPE 003F46 is firmly within the high-density polyethylene classification and at the characteristic density level for HDPE film grades. This density level drives the stiffness, moisture barrier, and tensile strength that make HDPE films preferred over LLDPE or LDPE in applications where film rigidity, rustling hand-feel, and strength-to-gauge ratio matter. It is slightly lower than IOCL’s injection-moulding and blow-moulding grades (0.952–0.960 g/cm³), which is typical for film-grade HDPEs where the molecular weight distribution is tuned for film processability rather than maximum crystallinity.
• Low Gel Content — Manufacturer-stated Feature: Gel content is not captured by a single numeric test value but is explicitly identified by IOCL as a defining feature of 003F46. Gel particles in blown film resin originate from localised high-molecular-weight or cross-linked polymer fractions that do not melt uniformly. In finished film, they appear as translucent or opaque spots, create thin points that reduce puncture resistance, and can cause film breaks during high-speed extrusion. IOCL’s Sclairtech solution polymerisation process produces a molecularly homogeneous polymer that minimises gel formation — a direct functional benefit for co-extrusion film lines and high-quality liner applications where defect-free production runs and consistent film structure across all layers are required.
• Tensile Strength at Yield — 29 MPa (MD) / 26 MPa (TD) (ASTM D882): Film tensile properties are reported in two directions: machine direction (MD, along the direction of film travel) and transverse direction (TD, perpendicular to film travel). The slightly higher MD yield strength reflects the molecular orientation introduced during film drawing in the machine direction. At 29 / 26 MPa, the grade delivers tensile yield values comparable with typical HDPE film grades and appropriate for packaging films and liners that must resist the stresses of filling, sealing, and handling without deforming at the yield point.
• Ultimate Tensile Strength — 45 MPa (MD) / 40 MPa (TD) (ASTM D882): The ultimate tensile strength — the stress at which the film fractures — of 45 MPa (MD) and 40 MPa (TD) indicates that films produced from 003F46 have significant residual strength after yielding. The difference between yield and ultimate tensile values is itself a measure of the strain-hardening capability of the film, which contributes to puncture resistance and toughness in dynamic loading situations such as drop impacts on filled bags and liner penetration by sharp edges.
• Elongation at Break — 780% (MD) / 950% (TD) (ASTM D882, IOCL TDS) / 800% (MD) / 950% (TD) (Instamine): The very high elongation at break values in both machine and transverse directions are characteristic of HDPE film produced by the blown film process. The higher TD elongation reflects the molecular orientation balance achieved at the blow-up ratio used for testing. These values confirm that the film will stretch substantially before fracturing — a property that contributes to puncture resistance, dynamic impact performance, and the film’s ability to conform to irregular contents without tearing.
• Dart Impact Strength — 2 g/μm (ASTM D1709, F50, 38 mm dart, 66 cm height): Dart impact strength is the standard measure of film’s resistance to a falling weight puncture — the most relevant test for bags and liners that must withstand contents falling against the film surface. At 2 g/μm, the film needs to be 2 grams thick per micron of gauge to resist puncture at the F50 failure level. For practical purposes, a 25 μm film would need the full surface mass of the film to absorb the impact; this value provides a basis for gauge specification against known drop weight requirements in the end-use application.
• Tear Strength — 0.4 g/μm (MD) / 0.45 g/μm (TD) (ASTM D1922): Tear strength measured by the Elmendorf method reflects resistance to tear propagation once a notch has initiated. The slightly higher TD tear value is typical for HDPE blown film and reflects the transverse molecular orientation. For liner applications where the film must resist tearing from sharp edges, contact stress, or rough surfaces, these values confirm that the film has the tear propagation resistance expected of a well-formed HDPE blown film grade.
• Processing Temperature — Barrel 180–200 °C / Melt 190–210 °C; BUR 2.0–3.0; Die Gap 0.75–2.5 mm (IOCL TDS): These manufacturer-stated parameters define the operating envelope for blown film processing of 003F46. The relatively narrow barrel temperature range of 180–200 °C reflects the need to maintain consistent melt homogeneity and viscosity for stable bubble formation. The BUR range of 2.0–3.0 covers most standard single and co-extrusion blown film configurations, and the die gap range of 0.75–2.5 mm accommodates a range of target film gauges.

Understanding the Key Properties of HDPE 010DP45U

• Melt Flow Index — 0.90 g/10 min (ASTM D1238, 190 °C / 5 kg): The MFI for 010DP45U is reported at 5 kg load, which is the standard test condition for blow-moulding and pipe-extrusion grades — not the 2.16 kg load used for injection-moulding and film grades. At 0.90 g/10 min under 5 kg, this is a low-flow, high-molecular-weight grade by design. Pipe extrusion requires a polymer melt that develops sufficient back-pressure to form a dimensionally stable tube without sagging or wall variation, and the low MFI reflects the molecular weight necessary for that extrusion stability. Higher-MFI pipe grades flow more easily but sacrifice the long-chain density that ESCR and toughness performance depend on. The 0.90 g/10 min value is characteristic of PE 63 pipe grades and consistent with the Hostalen bimodal grades in IOCL’s pipeline series.
• Density — 0.947 g/cm³ at 23 °C / 0.945 g/cm³ at 27 °C (ASTM D1505): IOCL’s technical documentation for this grade provides two density measurements at different temperatures, reflecting the thermal sensitivity of HDPE density measurement and the different reference conditions used in international and Indian standards. At 0.947 g/cm³, the grade sits in the lower-density range of HDPE pipe grades, consistent with the PE 63 classification’s property balance. The density governs crystallinity, and at this value the grade retains meaningful flexibility in the duct wall — relevant for directional drilling, tight-radius conduit laying, and installation conditions where the duct must negotiate non-linear paths without kinking.
• PE 63 Classification: PE 63 denotes the minimum required hydrostatic strength (MRS) of 6.3 MPa at 20 °C over a 50-year design life. This is the lowest pressure classification in the PE pipe system, below PE 80 and PE 100. For telecom OFC ducts, operating pressure is not the governing design requirement — the duct’s function is to protect optical fibre cables, not to contain pressurised fluid. The PE 63 classification is the correct and widely accepted specification for non-pressure OFC duct applications, providing regulatory compliance with standard telecom duct specifications without over-engineering to PE 80 or PE 100 performance levels that are unnecessary for the end use.
• ESCR (F50) — >600 h (ASTM D1693, 10% Igepal, Condition B): At greater than 600 hours, HDPE 010DP45U achieves the highest ESCR value in the Propel series reviewed here — exceeding the >500 h value of the high-ESCR blow-moulding grade HDPE 010DB50. ESCR is critical for buried pipe and conduit grades because soil, groundwater, and chemical backfill compounds can act as ESCR-active agents on the outer duct surface over the multi-decade service life of telecom infrastructure. The bimodal molecular architecture is the primary enabler of this ESCR performance: high-molecular-weight tie molecules in the bimodal distribution create the entanglement density that resists slow crack growth at the stress concentrations that develop in buried pipe under sustained loading.
• OIT — >30 min (ASTM D3895): Oxidative Induction Time measures the time to onset of oxidative degradation in a polymer sample exposed to oxygen at elevated temperature. It is a direct indicator of the residual antioxidant package in the material and serves as a quality indicator for both the as-supplied granule and the extruded pipe. An OIT exceeding 30 minutes confirms that 010DP45U contains a thermal stabiliser package robust enough to survive the extrusion process and retain meaningful antioxidant protection in the finished duct. For buried infrastructure with a 30-40 year design life, antioxidant depletion is a real long-term failure mechanism; OIT is the measurement that confirms the stabiliser package is present and effective.
• Notched Izod Impact Strength — 300 J/m (ASTM D256, 23 °C): At 300 J/m, HDPE 010DP45U is the toughest grade in the Propel injection/pipe/film series by this measure — and the value is not incidental. Bimodal Hostalen pipe grades are specifically engineered for high impact performance through the molecular architecture that distributes toughness across the pipe wall. For OFC ducts subjected to point loading from compaction equipment during backfill, dropped objects during handling, and cyclic ground movement in service, the ability to absorb and distribute impact energy without initiating brittle fracture is a critical long-term reliability attribute.
• Tensile Strength at Yield — 28 MPa (ASTM D638, Type IV): The 28 MPa tensile yield strength reflects the combined contribution of the crystalline and amorphous phases in the bimodal HDPE structure. For pipe grades, this value governs the resistance of the duct wall to hoop stress from soil overburden and handling loads. At 28 MPa, the duct wall resists sustained deformation under the ground pressures encountered in typical civil installation depths.
• Elongation at Break — >600% (ASTM D638): High elongation at break is a consistent attribute of bimodal HDPE grades and reflects ductile failure behaviour. A duct that deforms plastically before fracturing gives engineering margins that a brittle material does not — particularly relevant during installation when ducts may be bent around obstacles, handled roughly, or subjected to localized stress concentrations.
• Flexural Modulus — 850 MPa (ASTM D790): The 850 MPa flexural modulus defines the ring stiffness contribution of the pipe wall material. For non-pressure OFC ducts, ring stiffness determines resistance to pipe ovalization under soil loading — a critical factor for maintaining the circular cross-section needed to allow optical fibre cable blowing or pulling through the duct after installation.
• Vicat Softening Point — 126 °C (ASTM D1525): The 126 °C Vicat point confirms that the pipe wall retains its dimensional geometry and load-bearing cross-section well above the thermal conditions encountered in buried and above-ground duct service, including the elevated ground temperatures experienced in Indian summer conditions.
• Processing Temperature — 160–210 °C: The 160–210 °C extrusion window is the standard range for Hostalen bimodal pipe grades. The relatively wide window provides operational flexibility across screw configurations, die sizes, and line speeds used in PE pipe extrusion without approaching temperatures where thermal degradation of the UV and antioxidant stabiliser packages would occur.

• Melt Flow Index — 1.2 g/10 min (ASTM D1238, 190 °C / 2.16 kg): The MFI is measured at the 2.16 kg load convention used for injection moulding, film, and raffia grades — not the 5 kg load used for blow moulding and pipe grades. At 1.2 g/10 min, 012E50 flows more readily than the companion raffia grade 010E52 (0.90 g/10 min at the same load). In practice, this means 012E50 generates lower back-pressure at the die head at equivalent extrusion temperatures and screw speeds, making it better suited to the smaller die-hole geometries used in monofilament spinneret systems. For woven tape production, the higher MFI also provides a wider processing window at the lower end of the temperature range, which is useful for converters running high-speed tape lines where maintaining low melt temperature reduces the thermal degradation risk for a UV-stabilised grade.
• Density — 0.950 g/cm³ at 23 °C (ASTM D1505): The 0.950 g/cm³ density positions 012E50 at the lower end of the HDPE raffia grade density range. Lower density corresponds to lower crystallinity, which in the undrawn state produces a more ductile, flexible polymer with higher elongation at break and impact absorption before the orientation step. For monofilament yarn applications — fishing nets, mosquito net yarn, filter cloth — the lower crystallinity of 0.950 g/cm³ means the filament retains flexibility and knot strength after drawing, properties that are critical for net mesh structures that see repeated dynamic loading. For woven tape applications, the 0.950 g/cm³ density delivers slightly lower initial stiffness in the undrawn tape compared to denser grades, but orientation at the draw stage adds the tenacity needed for functional woven sack or tarpaulin fabric.
• Tensile Strength at Yield — 20 MPa (ASTM D638, 50 mm/min, compression-moulded Type IV): The 20 MPa yield strength on a compression-moulded specimen is the baseline isotropic tensile yield of the material before drawing. It is lower than the yield values reported for blow moulding grades in this series at comparable or higher densities, which is expected: the Sclairtech solution process and the moderate density of 0.950 g/cm³ produce a molecular structure optimised for orientation efficiency rather than maximum isotropic stiffness. The yield value of the drawn tape or filament after orientation will be significantly higher, determined by the draw ratio and thermal conditions of the converter’s line.
• Ultimate Tensile Strength — 37 MPa (ASTM D638, 50 mm/min, compression-moulded Type IV): The 37 MPa UTS on the compression-moulded specimen indicates the total load the isotropic material can sustain before fracture. For a raffia-family grade, this value is meaningful primarily as a grade comparison reference. After orientation in production, the UTS in the draw direction will exceed this value substantially, while the transverse direction will reflect the lower undrawn properties. The ratio of drawn-to-undrawn UTS is governed by the draw ratio and is an outcome the converter optimises for their target tape denier and fabric construction.
• Elongation at Break — >1000% (ASTM D638, compression-moulded Type IV): The >1000% elongation at break in the compression-moulded state is the single most directly useful property for predicting how far the material can be mechanically drawn before failure during tape or monofilament production. A grade with >1000% elongation in the unoriented state can in principle be drawn to very high ratios before the tape or filament breaks in the drawing zone, provided the drawing temperature and rate are within the grade’s orientation window. The >1000% value for 012E50 provides substantial headroom for converters to apply the draw ratios needed for their target tenacity while maintaining acceptable line breakage rates.
• Notched Izod Impact Strength — 400 J/m at 23 °C (ASTM D256, compression-moulded specimen): The 400 J/m Notched Izod value is the highest of any Sclairtech or Hostalen grade in the Propel series reviewed here, and it reflects the combination of 0.950 g/cm³ density (lower crystallinity, more flexible amorphous phase) and the Sclairtech solution process architecture at this MFI level. In a raffia-grade context, the Notched Izod on a compression-moulded specimen is not a container drop-test predictor — it is a characterisation of the unoriented polymer’s energy absorption capacity. For monofilament yarn applications, high toughness in the undrawn polymer is beneficial because it reduces the incidence of brittle fracture initiation at surface defects in the extrusion and drawing process. For woven fabric applications, the drawn tape’s impact behaviour in service is governed by the woven construction, not the isotropic Notched Izod value.
• Hardness — 65 Shore D (ASTM D2240): The 65 Shore D hardness reflects the surface hardness of the compressed, isotropic polymer at the 0.950 g/cm³ density level. In raffia and monofilament applications, Shore D is not a primary selection criterion, but it gives converters a reference for the surface quality of the extruded profile before drawing and for resistance to surface abrasion in the drawing and winding process.
• Processing Temperature — 180–250 °C: IOCL’s recommended processing window of 180–250 °C for 012E50 is wide by design, reflecting the variety of extrusion systems used in raffia and monofilament production. Tape extrusion with flat film dies typically operates toward the higher end of the range; monofilament spinneret systems may operate closer to 190–210 °C at the die for fine-denier filaments where precise temperature control is needed to prevent draw resonance. The wide manufacturer-stated window is the starting envelope; converters optimise within it for their specific machine, die geometry, and draw configuration. IOCL advises processing the material within six months of delivery and storing it below 50 °C in a dry, dust-free environment away from direct sunlight.

Understanding the Key Properties of HDPE 080M60U

• UV Stabilisation — Built-in Additive Package: This is the grade’s defining attribute and the reason for specifying 080M60U over any non-UV grade of similar MFI and density. The UV stabilisers work by absorbing or scavenging the UV radiation and free radicals that initiate photo-oxidative chain reactions in polyethylene. Without them, prolonged outdoor exposure leads to surface chalking, colour fade, loss of elongation, and ultimately brittle fracture under loads that the original moulded part would have handled without issue. The stabiliser package in 080M60U is formulated to extend service life in open-environment conditions where crates and pails face daily UV cycling and weather exposure.
• ESCR — Good Environmental Stress Crack Resistance: ESCR is the resistance of a moulded HDPE part to cracking when it is under mechanical stress and in contact with an ESCR-active medium such as a surfactant, detergent, paint solvent, or cleaning agent. For paint pails specifically, the combination of the filled container weight, residual moulding stresses, and the chemical nature of the pail contents makes ESCR a critical selection criterion. IOCL’s explicit ESCR characterisation for 080M60U distinguishes it from standard crate grades and positions it for the pail and outdoor container segment where this property matters.
• Melt Flow Index — 8.0 g/10 min (ASTM D1238, 190 °C / 2.16 kg): The MFI of 8.0 g/10 min supports efficient filling of the deep, ribbed cavities common in industrial crate and pail moulds. It delivers a balance between fill speed and molecular weight retention — high enough for good productivity, low enough to preserve the mechanical and ESCR performance that outdoor applications require.
• Density — 0.960 g/cm³ (ASTM D1505, 23 °C): The 0.960 g/cm³ density reflects a high degree of crystallinity, which underpins the stiffness, chemical barrier, and moisture resistance of the moulded crate or pail. High crystallinity also contributes positively to ESCR by reducing the free volume in the polymer matrix through which stress-cracking agents can diffuse.
• Tensile Strength at Yield — 25 MPa / Elongation at Break — >800% (ASTM D638): The 25 MPa tensile yield strength provides structural integrity under the loads that filled crates and pails experience in transit and stacking. The high elongation at break of over 800% confirms ductile failure behaviour, meaning that parts deform plastically before fracturing — a property that contributes to impact and ESCR performance in service.
• Flexural Modulus — 850 MPa / Flexural Yield Strength — 20 MPa (ASTM D790): At 850 MPa, moulded crate walls and pail bases resist bending under stacked loads. This stiffness level ensures that crates maintain their shape in racking and palletised storage systems, and that pails do not deform or oval when handled by their handles under full fill weight.
• Notched Izod Impact Strength — 90 J/m (ASTM D256, 23 °C): Outdoor crates and pails are exposed to drop impacts, rough handling, and impact from loading equipment. At 90 J/m, HDPE 080M60U provides meaningful toughness at notch-sensitive weld lines, corner features, and rim sections where cracking would otherwise initiate under sudden mechanical load.
• Hardness — 55 Shore D (ASTM D2240): A Shore D of 55 gives crate and pail surfaces a firm, scuff-resistant finish that withstands the abrasion and surface contact of warehouse and yard environments without marking easily.
• Vicat Softening Point — 127 °C (ASTM D1525): The 127 °C Vicat point is directly relevant to outdoor products in India where surface temperatures on dark-coloured or black crates left in direct sun can rise substantially above ambient air temperature. At 127 °C, moulded parts retain dimensional stability well above the thermal conditions encountered in outdoor storage yards, uncovered logistics environments, and agricultural field use.
• Processing Temperature — 180–215 °C: The standard HDPE injection processing window applies to 080M60U, providing compatibility with existing machine and mould configurations used for non-UV crate and pail grades.
