Polypropylene is a polymer formed by the addition of propylene.White waxy material, transparent and light in appearance.The density is 0.89 ~ 0.91g/cm3, flammable, the melting point is 165℃, the softening is around 155℃, the operating temperature range is -30 ~ 140℃ .Under 80℃ can withstand acid, alkali, salt solution and a variety of organic solvents, can be decomposed under high temperature and oxidation.Polypropylene is widely used in clothing, blankets and other fiber products, medical equipment, cars, bicycles, parts, transport pipes, chemical containers and other production, also used in food, medicine packaging.
Polypropylene resin is one of the four general thermoplastic resins (polyethylene, polyvinyl chloride, polypropylene, polystyrene). The production process of polypropylene mainly went through several development stages of solvent method, solution method, liquid phase bulk method (combined with liquid phase and gas phase) and gas phase method.The process methods used to produce polypropylene in the world are mainly divided into the following categories: solvent method, solution method, liquid phase bulk method (including liquid phase combination) and gas phase method.
Polypropylene Sheet is mainly used in food packaging, household goods, automobiles, optical fiber and other fields in China.The biggest use of polypropylene in China is in woven bags, packaging bags, bundling rope and other products, accounting for about 30% of the total consumption.In recent years, with the development of polypropylene injection molding products and packaging film, the proportion of polypropylene used in weaving products has decreased, but it is still the most polypropylene consumption area.Injection molding products are the second largest consumer segment of polypropylene in China, accounting for about 26% of total consumption. It is also one of the regions with the greatest demand for polypropylene pp sheet in the future.Another major area of domestic consumption of polypropylene is film, accounting for about 20% of total consumption, mainly BOPP (bidirectional tensile polypropylene film) film.In the next few years, the proportion of textile products will gradually decline, while the proportion of injection products, pipes and plates will increase. According to the forecast of experts on the development of polypropylene industry, the demand for polypropylene sheet in China is likely to reach about 23.7 million tons by 2020.Textile products, injection products and film are still the main demand areas of polypropylene pp sheet in China, and the annual demand of pipe, plate, fiber and other fields is growing rapidly, the domestic demand for PP Sheet is also growing rapidly.High speed mapping BOPP film, pipe, thin non-woven, high transparent food containers and other special materials market development prospects are good.
