Zhongtai Suspension Pvc Resin For K66
Description:
Polyvinyl chloride, abbreviated as PVC Resin, is a polymer formed by the polymerization of vinyl chloride monomer (VCM) under the action
of peroxides, azo compounds and other initiators or under the action of light and heat according to the free radical polymerization reaction mechanism. Vinyl chloride homopolymer and vinyl chloride copolymer are collectively referred to as vinyl chloride Resin. PVC is a white powder with an amorphous structure with a small degree of branching. Its glass transition temperature is 77~90℃, and it starts to decompose around 170℃. It has poor stability to light and heat. Decomposition produces hydrogen chloride, which is further autocatalyzed and decomposed, causing discoloration, and the physical andmechanical properties also decline rapidly. In practical applications, stabilizers must be added to improve the stability to heat and light.
Mainly used to
1. PVC profile
Profiles are the largest area of PVC consumption in my country, accounting for about 25% of total PVC consumption. They are mainly used to make doors and windows and energy-saving materials, and their application volume is still increasing significantly across the country. In developed countries, the market share of plastic doors and windows is also the highest, for example, Germany is 50%, France is 56%, and the United States is 45%.
2. Polyvinyl chloride pipe
Among many polyvinyl chloride products, polyvinyl chloride pipes are its second-largest consumption area, accounting for about 20% of its consumption. In my country, polyvinyl chloride pipes are developed earlier than PE pipes and PP pipes, with more varieties, excellent performance, and a wide range of applications, and occupy an important position in the market.
