HDPE ZRCC PE M577‑S (HSGC7260)
HDPE Zhenhai Refining & Chemical PE M577‑S (HSGC7260) Resin
Material Introduction: HDPE PE M577‑S (also named HSGC7260) from Zhenhai Refining & Chemical is a drawing‑grade high‑density polyethylene. Its medium‑low melt flow rate and proper density make it highly suitable for various woven products. Satisfactory tensile strength, excellent elongation at break and chemical resistance meet fundamental material requirements for relevant applications.
Main Applications
Packaging materials: woven bags, FIBC bulk bags, cargo bags for packing fertilizer, cement, grain, chemical raw materials, etc.
Ropes and nets: ropes, fishing net filaments, safety nets.
Industrial fabrics: base fabric for geotextiles and tarpaulins.
