PVC Resin

Polyvinyl chloride (PVC) is a vinyl chloride monomer (VCM) in the peroxide, azo compounds and other initiators or under the action of light and heat according to the free radical polymerization reaction mechanism of polymer polymerization.Vinyl chloride homopolymer and vinyl chloride copolymer are called vinyl chloride resins.

The thermoplastic high-molecular polymer made by the suspension polymerization of vinyl chloride monomer. The molecular formula :- (CH2 - CHCl) n - (N: degree of polymerization, N= 590 ~ 1500). It is the most widely raw material used in plastic production. It has good chemical stability, corrosion resistance and water resistance.
