Polypropylenes is a polymer of propylenes by addition polymerization. It is white waxy material, transparent and light in appearance. Chemical formula is (C3H6) N, density 0.89 ~ 0.91g/cm3, flammable, melting point 189oC, softening at 155oC or so, the use of temperature range of -30 ~ 140oC. Under 80oC, it can resist the corrosion of acid, alkali, salt liquid and various organic solvents, and can decompose under the action of high temperature and oxidation. PolypropyleneS is widely used in the production of clothing, blankets and other fiber products, medical instruments, automobiles, bicycles, parts, pipelines, chemical containers, and also used in food and drug packaging.
