Polyethylene resin as the main raw material polypropylene Which is better, adding a variety of additives polypropylene specifications, surface (two-sided) composite woven polypropylene, the calendering process forming a polymer composite web (sheet). PVC waterproof material is polyethylene-based raw material to manufacture polypropylene, polyethylene, non-toxic, so PVC waterproof material is also non-toxic. PVC was poisonous. China said the PP polypropylene producers to isotactic polypropylene as raw material obtained by spinning synthetic fiber, chemical fiber lightest varieties; strength of 35 ~ 62cN / dtex; wear resistance second only polyamide fiber; resistant good corrosion resistance, especially inorganic acids polypropylene manufacturers | Shouguang Tianxiang waterproof (certified) | polypropylene provided by Shouguang City Tianxiang waterproof material plant.
