IOCL Propel LLDPE 010L22S

IOCL Propel LLDPE 010L22S is a linear low-density polyethylene (LLDPE) grade made for drip lateral pipe. It is produced using Sclairtech solution polymerisation technology with butene as the comonomer. The grade has a melt flow index of 1.1 g/10 min and density of 0.922 g/cm³.

The grade meets the requirements of IS 12786:1989 when compounded with carbon black for PE-25 drip lateral pipe. Its ESCR exceeds 1000 hours — the highest stress crack resistance value in the IOCL Propel LLDPE range. This makes it suitable for agricultural pipe systems that are exposed to soil chemicals, fertilisers, and UV over extended service cycles.

The natural (unpigmented) granule must be dry-blended or melt-compounded with 2.5 ± 0.5% carbon black by mass, verified per IS 2530, before pipe extrusion. The compounded material delivers the UV resistance and PE-25 classification required for drip lateral pipe.

Technical Insights

• MFI 1.1 g/10 min (190°C/2.16 kg), ASTM D1238 — Low melt flow gives controlled extrusion. The pipe wall holds consistent thickness at standard line speeds.
• Density 0.922 g/cm³, ASTM D1505 — Low-density LLDPE range. Short-chain butene branches reduce crystallinity and create a flexible, tough pipe.
• ESCR >1000 h, ASTM D1693 (F50, 10% Igepal) — The highest ESCR value in the Propel LLDPE series. Resists stress cracking caused by fertiliser chemicals, herbicides, and soil contaminants in drip irrigation systems.
• Tensile Strength at Yield ~11–12 MPa, ASTM D638 — Adequate load resistance for buried lateral pipe without brittleness.
• Elongation at Break >600%, ASTM D638 — High elongation absorbs ground movement and installation stress without cracking.
• Flexural Modulus ~350–400 MPa, ASTM D790 — Lower stiffness than HDPE grades. The pipe is flexible enough to coil for transport and uncoil without kinking.
• Vicat Softening Point ~104–108°C, ASTM D1525 — Suitable for standard agricultural conditions. Not designed for hot-water pipe.
• Carbon black compounding required — 2.5 ± 0.5% by mass, IS 2530 — This step is mandatory for IS 12786:1989 PE-25 classification. The natural grade without carbon black does not qualify as PE-25.
• Sclairtech solution polymerisation — Narrow molecular weight distribution, clean and consistent melt behaviour, low gel content. Suited for thin-wall, small-diameter lateral pipe.

Applications

Drip Irrigation Lateral Pipe (IS 12786:1989, PE-25)

LLDPE 010L22S is primarily used for drip lateral pipe — the thin-wall small-diameter tube that runs through agricultural fields and delivers water to crop root zones. These pipes are buried in soil, exposed to fertilisers and herbicides, and often remain under pressure for months without interruption. The grade’s ESCR of more than 1000 hours means the pipe wall resists chemical-induced cracking over long field life. The low density (0.922 g/cm³) and high elongation (>600%) allow the pipe to flex with soil movement and survive coiling, uncoiling, and rough installation. Once compounded with 2.5 ± 0.5% carbon black per IS 2530, it qualifies as a PE-25 pipe material under IS 12786:1989 — the Indian standard governing drip lateral pipe.

Agricultural Micro-Irrigation Components

Beyond the lateral pipe itself, LLDPE 010L22S is used for associated micro-irrigation fittings — connectors, T-joints, end caps, and emitter bodies — where the same flexibility and ESCR performance are needed. Agricultural pipe systems operate across temperature cycles and soil chemistry variations. The material’s toughness and crack resistance make it a reliable base material for injection-moulded fittings that connect to PE-25 lateral pipe runs.

Film and Flexible Packaging (Natural Grade)

In its natural (uncompounded) form, LLDPE 010L22S can be used for flexible film — stretch wrap, agricultural mulch film, and general-purpose packaging film — where high elongation, puncture resistance, and good clarity in thin gauge are needed. The low MFI supports blown film processing with standard LLDPE equipment. Applications that need pigmentation or UV stabilisation can incorporate masterbatch at the extrusion stage.

Flexible Pipe and Tubing (Non-IS 12786 Applications)

Where IS 12786:1989 certification is not required, the grade serves as a flexible polyethylene pipe base for garden hose, micro-sprinkler connectors, and light-duty fluid transfer tubing. The combination of flexibility, ESCR, and consistent melt processing makes it a versatile base resin for small-diameter flexible pipe in irrigation and industrial fluid lines.

Comparable Alternatives

LLDPE 010L22S vs Comparable Drip Pipe Grades

LLDPE grades for PE-25 drip lateral pipe share similar targets: MFI near 1.0–1.2 g/10 min, density around 0.922 g/cm³, and ESCR above 500 hours. The grades below are the closest alternatives available in India.

Reliance JD22010 is the most direct match. MFI 1.1 g/10 min, density 0.922 g/cm³, ESCR >1000 h. The specifications are nearly identical to IOCL 010L22S across all key parameters. Both target PE-25 drip lateral pipe and require carbon black compounding for IS 12786:1989 compliance. The choice between them typically comes down to supply availability, supplier credit terms, and regional logistics.

Reliance LL20DS010 is a slightly higher MFI drip pipe grade (1.2 g/10 min) at similar density. The marginally higher flow rate may suit faster extrusion lines but can require die setting adjustments for dimensional control on thin-wall pipe.

GAIL D22S010 / D22S010A are GAIL’s PE-25 drip lateral grades. MFI approximately 1.0 g/10 min, density 0.922 g/cm³. Very close to 010L22S in processing behaviour. GAIL supply is typically strongest in central and western India.

HMEL D0120L is HMEL’s equivalent drip lateral grade with comparable MFI and density. Processing characteristics are similar. HMEL supply is concentrated in North India through Bathinda refinery output.

Haldia 71601D is an older Haldia Petrochemicals drip grade. It meets PE-25 requirements but is available primarily in eastern and southern India. Processing characteristics are broadly similar.

Borouge LE2270 is a UAE-origin LLDPE import grade used in India for drip pipe applications. It may offer different comonomer chemistry and slightly different flexibility characteristics. Import pricing and availability vary with exchange rates and freight cycles.

For Indian buyers, IOCL 010L22S, Reliance JD22010, and GAIL D22S010A are the highest-supply domestic options. All require carbon black compounding before IS 12786:1989-compliant pipe extrusion.

Common Search Variants

Buyers search for this grade as Propel LLDPE 010L22S, IOCL 010L22S, LLDPE drip pipe grade India, PE-25 LLDPE IS 12786, and IOCL LLDPE for drip irrigation. Some procurement teams also search by polymer family — butene LLDPE 0.922 density or LLDPE MFI 1.1 drip grade.
