Basic Physical Properties: Wide Process Window & Stable Mass Production
With moderate MFR and steady melt flow, 5000S offers an extra-wide processing window for high-speed flat yarn lines. It enables even plasticization and stable melt tension to reduce broken filaments, uneven thickness and fuzzy threads, lifting yield and efficiency. Ultra-low ash and high pellet purity support extrusion, blown film and injection molding for diversified mass manufacturing.
Mechanical Properties: High Rigidity, Wear & Weather Resistance
Its high-density structure balances rigidity and mechanical performance. High tensile strength and 500% elongation resist heavy load deformation and fracture. Great notched impact and good ESCR withstand temperature swings, friction and long outdoor exposure, extending the service life of outdoor plastic products.
Processing Technology & Core Application Scenarios
Primarily developed for raffia flat/round yarn extrusion; also compatible with extrusion, blown film and injection molding for flexible multi-product production.
· Woven Fiber Goods: Industrial woven bags, packaging flat/round yarn, fishing nets, safety ropes, geotextiles
