The characteristic of the PP toilet seat

Polypropylene, abbreviated as PP, is a colorless, odorless, non-toxic and translucent solid substance(PP toilet seat). Polypropylene is a kind of thermoplastic synthetic resin with excellent performance. It 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 properties, polypropylene has been rapidly developed and applied in many fields such as machinery, automobile, electronics and appliances, construction, textile, packaging, agriculture, forestry and fishery, food industry and so on. In recent years, with the rapid development of China's packaging, electronics, automobile and other industries, it has greatly promoted the development of China's industry. And because of its plasticity, polypropylene is gradually replacing wood products, and high strength, toughness and high wear resistance have gradually replaced the mechanical function of metal. In addition, polypropylene has good grafting and composite functions, and has great application space in concrete, textile, packaging, agriculture, forestry and fishery.

（PP toilet seat)Mice were intragastrically administered with a dose of 8G / kg for 1 ~ 5 times, and no obvious poisoning symptoms were caused. Rats inhaled the decomposition products of polypropylene heated to 210 ~ 220 ℃ for 30 times, 2h each time, and showed irritation of ocular mucosa and upper respiratory tract. Like polyethylene, it is forbidden to use its recycled products to contain food.
