Gail HDPE G Lex W52ASR009N

Gail HDPE G‑Lex W52ASR009N is a UV‑stabilized high‑density polyethylene (HDPE) grade from GAIL (India) Limited designed specifically for monofilament extrusion. It is positioned for medium‑tenacity yarn used in ropes, twines, and fishing/sporting nets, where buyers need a dependable balance of linear tensile strength and knot strength, plus stable processing on monofilament extrusion and drawing lines.

GAIL describes W52ASR009/W52ASR009N as “High Density Polyethylene for Monofilament Extrusion,” emphasizing good processability and an optimum balance of strength and elongation—a practical combination for monofilaments that must draw consistently without becoming brittle, while still holding up under repeated tension and knotting.

W52ASR009N is the UV‑stabilized variant (vs. W52ASR009), intended to improve performance in outdoor exposure and storage/handling conditions common in netting, marine, agriculture, and general cordage applications.

The grade is stated to conform to IS 7328‑3‑LB‑HXDA of IS 7328:2020 (natural resin designation) for monofilament and related products. It is supplied as natural‑colour pellets in 25 kg woven sacks.

Technical insights

• Melt Flow Index (I2, 190°C/2.16 kg): 0.45 g/10 min (typical). A medium MFI supports stable extrusion and draw‑down for monofilament, helping balance throughput with filament integrity.
• Density (23°C): 0.964 g/cm³ (typical). Higher density typically correlates with higher stiffness and strength—useful for ropes/twines that must retain shape and resist deformation.
• Tensile strength at yield: 260 kg/cm² (typical). Indicates the material’s ability to carry load before permanent deformation—important for cordage under continuous tension.
• Elongation at yield: 9% (typical) and elongation at break: >600% (typical). This combination signals a practical balance: controlled stretch under working load, with high ultimate ductility to reduce sudden brittle failure.
• Flexural modulus: 11000 kg/cm² (typical). Reflects stiffness; supports monofilaments that need firmness and dimensional stability in ropes and net structures.
• Vicat softening point: 124°C (typical). Suggests good heat resistance for many end‑use environments and helps maintain performance in warmer outdoor conditions.
• Processing guidance (barrel temperature): 210–270°C. Typical monofilament extrusion temperature window provided for this grade family; actual settings depend on line design, die, draw ratio, and cooling.

Applications

Medium‑tenacity ropes and cordage: W52ASR009N is commonly selected for rope and cordage producers who want a UV‑stabilized HDPE monofilament that draws reliably and delivers a strong balance of tensile performance and knot integrity. It fits general‑purpose industrial and agricultural ropes where consistent filament quality matters.

Twines (agri, packaging, general utility): For twine manufacturers, the grade’s medium‑flow profile and strength/elongation balance supports monofilaments that can be knotted repeatedly without becoming overly brittle, while still providing the stiffness needed for clean winding and handling.

Fishing nets and sporting nets: In fishing and sporting net applications, UV exposure and moisture are constant stressors. W52ASR009N’s UV stabilization is positioned to improve outdoor durability, making it a practical choice for netting producers seeking stable performance across storage and field use.

Comparable alternatives

Within GAIL’s own portfolio, W52ASR009 is the closest comparable grade as the non‑UV version; W52ASR009N is typically preferred when outdoor exposure, longer storage, or weathering resistance is a priority.

For applications that demand higher tenacity, GAIL positions W55A004/W55A004N as grades aimed at high‑strength yarn, ropes, and fishing nets. These may be considered when the end product requires higher strength targets, but processors should validate draw behavior, knot performance, and full property match against the relevant manufacturer datasheets.

For producers evaluating tape vs. monofilament routes, W52A009/W52A009N are positioned more toward tape and tarpaulin (with some monofilament use in certain fishing‑net constructions). In practice, W52ASR009N is the more direct fit when the requirement is monofilament‑based ropes/twines/nets rather than stretched tape applications.

In all cases, treat alternatives as comparable options rather than drop‑in equivalents unless MFI, density, tensile/elongation, and end‑use performance requirements are matched and validated on your line.
