High temperature resistance. PP material refers to polypropylene, which is a thermoplastic resin material polymerized from propylene. It is a white waxy material. It is usually translucent without any smell and toxicity. Its melting point is 189 ℃, which is relatively high-temperature resistant. Does PP material have high temperature resistance? PP material has chemical resistance, heat resistance, electrical insulation, high strength mechanical properties and good high wear resistance.
PP materials are widely used in the production of fiber products, automobiles, bicycles, parts, transmission pipelines, chemical containers and so on, as well as food and drug packaging.
The production process of PP material includes solvent polymerization, solution polymerization, liquid phase bulk method and gas phase bulk method. （ppCaiLiaoNaiGaoWenMa）
