As we all know, ordinary PE material is characterized by good elasticity but poor wear resistance; And PP material is characterized by wear resistance, but poor elasticity. Many foreign spiral protective covers are made of PE material, which is very poor in recovery.
But our company produces the spiral case and the Shanghai institute of rubber joint research and development of modified formula, has both the flexibility of PE, and the wear resistance of PP (China petrochemical PP particles), and the raw materials melting point 280 ℃, melt index was 1.9, compared with other manufacturers use ordinary polypropylene material, melt index was only 1.3. Because the material we use has a lower molecular weight, our products have a finer, smoother appearance and more precise shape.
