Polyvinyl Chloride
Polyvinyl chloride (PVC) is a thermoplastic resin made from vinyl chloride monomer (VCM) through a polymerization reaction. It is one of the world's most produced general-purpose plastics. Depending on the amount of plasticizer added, it can be divided into rigid PVC and flexible PVC, and is widely used in building materials, packaging, electronics, medical and other fields.
