Recently, the price of PVC resin has soared to the highest in history. PVC stands for polyvinyl chloride, or PVC (Polyvinyl chloride) in English, which is the initiator of vinyl chloride monomer (VCM) in peroxides, azo compounds and other initiators; or Under the action of light and heat, it is a polymer polymerized according to the mechanism of free radical polymerization. Vinyl chloride homopolymer and vinyl chloride copolymer are collectively referred to as vinyl chloride resin. The material is an amorphous material.
