Injection grade drawing grade extrusion grade transparent polypropylene raw material
Polypropylene, abbreviated as PP, is a polymer formed by addition polymerization of propylene. It is white waxy material with transparent and light appearance. The chemical formula is (C3H6) n, the density is 0.89 ～ 0.91g/cm3, it is flammable, the melting point is 189 ℃, it is softened at about 155 ℃, and the use temperature range is - 30 ～ 140 ℃. It can resist the corrosion of acid, alkali, salt solution and various organic solvents below 80 ℃, and can be decomposed under high temperature and oxidation. Polypropylene is a kind of thermoplastic synthetic resin with excellent performance. It is a colorless and translucent thermoplastic light general-purpose plastic. It has chemical resistance, heat resistance, electrical insulation, high strength mechanical properties and good high wear resistance processing performance. It is widely used in the production of clothing, blankets and other fiber products, medical equipment, automobiles, bicycles, parts, transmission pipelines, chemical containers, and food and drug packaging.
