Gail HDPE G Lex W52ASR009
Gail HDPE G‑Lex W52ASR009 is a high‑density polyethylene (HDPE) grade for monofilament extrusion manufactured by GAIL (India) Limited. It is positioned as especially suitable for medium‑tenacity yarn used in monofilament‑based ropes, twines, fishing nets, and sporting nets, offering good processability with an optimum balance of strength and elongation.
In practical terms, W52ASR009 is selected by converters who need a monofilament resin that runs reliably on extrusion and drawing lines, while producing yarn that performs well under real‑world loads (tension, knotting, handling, and outdoor use). Compared with higher‑tenacity monofilament grades, it is positioned for medium‑duty cordage and netting where stable processing and balanced mechanical behavior are priorities.
W52ASR009 belongs to the G‑Lex HDPE family produced via GAIL’s CX‑slurry process. It is supplied as natural‑colour pellets in 25 kg woven sacks and should be stored dry at temperatures below 50°C.
Technical insights
- Melt Flow Index (I2, 190°C/2.16 kg): 0.45 g/10 min (typical). A medium MFI supports good processability and throughput in monofilament extrusion, while still allowing strength development after drawing.
- Density (23°C): 0.964 g/cm³ (typical). Higher density HDPE generally supports stiffness and strength in drawn structures, useful for ropes and netting.
- Tensile strength at yield: 260 kg/cm² (typical). Indicates resistance to yielding under load; relevant for cordage that sees sustained tension.
- Elongation at yield: 9% (typical). Helps indicate early deformation behavior and stiffness/stretch balance.
- Elongation at break: >600% (typical). High elongation at break supports toughness and helps reduce brittle failure during use and knotting.
- Flexural modulus: 11,000 kg/cm² (typical). A stiffness indicator that can support dimensional stability and “body” in monofilament products.
- Vicat softening point: 124°C (typical). Helps indicate thermal softening behavior relevant to service and downstream handling.
- Processing guidance (typical): Barrel temperature 210–270°C as a starting range for monofilament extrusion; optimize based on die design, output rate, quench conditions, and draw ratio.
Applications
Medium‑duty ropes and twines (monofilament‑based). W52ASR009 is designed for medium‑tenacity yarn used in ropes and twines where converters want a balance of linear strength and controlled elongation, along with good processing stability on extrusion and drawing lines.
Fishing nets and sporting nets. The grade is positioned for fishing/sporting net monofilament where toughness and elongation help reduce breakage during installation and use. It is commonly searched as HDPE monofilament granules/dana for net yarn.
General cordage and netting for outdoor service. For applications exposed to outdoor handling and repeated mechanical stress, W52ASR009 is selected when a medium‑tenacity performance level is sufficient and consistent processing is a priority.
Comparable alternatives
The closest comparisons are within GAIL’s own monofilament/raffia portfolio:
- G‑Lex W52ASR009N (UV‑stabilized pair grade). This is the nearest related grade name; treat interchangeability as end‑use dependent (UV exposure requirements, additive package, and performance targets should be confirmed against manufacturer documentation).
- G‑Lex W55A004 / W55A004N (high‑tenacity monofilament grades). These are positioned for higher‑tenacity yarn for fishing nets and ropes. They may not be direct substitutes if the buyer’s target is medium tenacity and easier processing.
- G‑Lex W52A009 / W52A009N (tape/raffia‑oriented grades). These are often used for stretched tape/raffia applications and can appear in similar search journeys, but they are not the same positioning as a rope/twine monofilament grade.
Across India, other suppliers offer HDPE monofilament/raffia grades, but direct equivalence to G‑Lex W52ASR009 is not confirmed unless matched against manufacturer TDS data (MFI, density, tensile/elongation, stiffness) and validated on your extrusion + drawing line.
