Ethylene Based PVC SINOPEC S1000 K65 67

Ethylene Based PVC S1000 K65 67 Description: Polyvinyl chloride, abbreviated as PVC S1000, 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.   PVC S1000 Mainly used to:…
