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.
PP(Polypropylene)granules is a nontoxic, odorless, odorless, tasteless, creamy, high crystalline polymer with a density of only 0.90 --" 0.91g /cm3, "one of the lightest plastics available. It is particularly stable for water, with a water absorption rate of 0.01% and a molecular weight of about 81,150,000. Good molding performance, but due to large shrinkage rate (1%~2.5%), thick wall,products are easy to sag, it is difficult to meet the requirements for some parts with high dimensional precision, and the surface of products is glossy.
In addition to GPPS Resin, we also produce Resin Raw Material,HIPS Resin,ABS Resin,PP Resin.We will continue to innovate, provide customers with better products and services, and build a better future together.
