PP material for blow machine

Polypropylene is a polymer formed by addition polymerization of propylene. It is a white waxy material with a transparent and light appearance. The chemical formula is (C3H6)n, the density is 0.89~0.91g/cm3, [1] It is flammable, with a melting point of 189℃, softening at about 155℃, and the operating temperature range is -30~140℃[2]. It is resistant to corrosion by acids, alkalis, salt solutions and a variety of organic solvents below 80°C, and can be decomposed under high temperature and oxidation. Polypropylene is widely used in the production of clothing, blankets and other fiber products, medical equipment, automobiles, bicycles, parts, pipelines, chemical containers, etc. It is also used in food and pharmaceutical packaging.

Polypropylene is abbreviated as PP, which is a colorless, odorless, non-toxic, translucent solid substance. [4] Polypropylene is a thermoplastic synthetic resin with excellent performance, and is a colorless and translucent thermoplastic lightweight general-purpose plastic. With chemical resistance, heat resistance, electrical insulation, high-strength mechanical properties and good high wear-resistant processing performance, this has made polypropylene rapidly used in machinery, automobiles, electronics, construction, textiles, packaging since its inception. , Agriculture, forestry, fishery, food industry and many other fields have been widely developed and applied. [4] In recent years, with the rapid development of China's packaging, electronics, and automobile industries, it has greatly promoted the development of China's industry. [5] And because of its plasticity, polypropylene materials are gradually replacing wooden products, and high strength, toughness and high wear resistance have gradually replaced the mechanical functions of metals. In addition, polypropylene has good grafting and compounding functions, and has huge application space in concrete, textile, packaging, agriculture, forestry and fishery.
