Product Details
Polypropylene, abbreviated as PP, is a polymer formed by the addition reaction of propylene. It is a white waxy material with a transparent and lightweight appearance. The chemical formula is (C3H6) n, with a density of 0.89~0.91g/cm3. It is flammable, has a melting point of 189 ℃, and softens at around 155 ℃. The temperature range for use is -30~140 ℃. It can withstand corrosion from acids, alkalis, salt solutions, and various organic solvents below 80 ℃, and can decompose under high temperature and oxidation. Polypropylene is a high-performance thermoplastic synthetic resin, which is a colorless and translucent thermoplastic lightweight 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 fiber products such as clothing and blankets, medical devices, automobiles, bicycles, parts, transportation pipelines, chemical containers, and so on
In response to the poor impact resistance, poor weather resistance, poor surface decoration of polypropylene at low temperatures, and the gap between its functionality in electrical, magnetic, optical, thermal, and combustion aspects and actual needs, modifying polypropylene has become the most active and fruitful field in plastic processing development.
