The specific gravity is 0.95. Polypropylene plastic particles refer to polypropylene, which is a polymer formed by the addition polymerization reaction of propylene.
It can resist the corrosion of acids, alkalis, salt liquids and various organic solvents below 80℃, and can decompose under high temperature and oxidation. Polypropylene is widely used in the production of clothing, blankets and other fiber products, medical equipment, automobiles, bicycles, parts, transportation pipelines, chemical containers, etc.
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 metal. In addition, polypropylene has good grafting and composite functions, and has huge application space in concrete, textiles, packaging, agriculture, forestry and fishery.
