PVC SG5
Introduction
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.
