Polypropylene for short is a colorless, odorless, non-toxic, translucent solid substance. Polypropylene is a thermoplastic synthetic resin with excellent properties. It is a colorless and translucent thermoplastic lightweight general-purpose plastic. Polypropylene (PP) is a polymer produced by the addition polymerization of propylene. It is a white waxy material with a transparent and light appearance.
PP is resistant to the corrosion of acid, alkali, salt solution and many organic solvents below 80 ℃, and can decompose under high temperature and oxidation. Having chemical resistance, heat resistance, electrical insulation, high mechanical strength properties and good processing properties of high wear resistance. PP has plasticity and is gradually replacing wooden products. High strength, toughness and high wear resistance have gradually replaced the mechanical functions of metals. In addition, polypropylene has good grafting and composite functions, and has huge application space in concrete, textile, packaging, agriculture, forestry and fishery.
Polypropylene is widely used in production of clothing, blankets and other fiber products, medical devices, automobiles, bicycles, parts, pipelines, chemical containers, also for food and pharmaceutical packaging.
