what is the meaning of pvc
Polyvinyl chloride, more correctly but unusually poly(vinyl chloride), commonly abbreviated PVC, is the third-most widely produced synthetic plastic polymer, after polyethylene and polypropylene.PVC comes in two basic forms: rigid (sometimes abbreviated as RPVC) and flexible.The rigid form of PVC is used in construction for pipe and in profile applications such as doors and windows. It is also used for bottles, other non-food packaging, and cards (such as bank or membership cards).olyvinyl chloride is produced by polymerization of the vinyl chloride monomer (VCM), as shown. About 80% of production involves suspension polymerization. Emulsion polymerization accounts for about 12% and bulk polymerization accounts for 8%.
