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.It is widely used in building materials, industrial products, daily necessities, floor leather, floor tile, artificial leather,
pipe, wire and cable, packaging film, bottle, foaming material, sealing material, fiber and other aspects.
