polyvinyl chloride refers to a thermoplastic resin formed by free radical polymerization of vinyl chloride monomer (VCM) under the action of initiator such as peroxide and azo compound.
Different additives can be added according to different purposes, and polyvinyl chloride plastics can exhibit different physical and mechanical properties. Adding appropriate amount of plasticizer to polyvinyl chloride resin can make a variety of hard, soft and transparent products.
