How is PVC formed?
PVC is produced by polymerization of the vinyl chloride monomer. PVC comes in two basic forms: Rigid (sometimes abbreviated as RPVC) and flexible. It is the world’s third-most widely produced synthetic plastic polymer, after PE and PP. About 40 million tons are produced per year.
What is PVC resin made from?
vinyl chloride monomer
Polyvinyl 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%.
Where does PVC resin come from?
PVC is manufactured from petroleum. The production process also uses sodium chloride. Recycled PVC is broken down into powder or small chips with the impurities removed. The resulting product is refined to make pure white PVC.
What is made from PVC?

What approx percentage of chlorine is present in the homopolymer of vinyl chloride?
57% chlorine
Explanation: The homopolymer of vinyl chloride contains nearly 57% chlorine.
What does K value mean for PVC?
K value (viscosity), is an empirical parameter closely related to intrinsic viscosity, often defined in slightly different ways in different industries to express viscosity based estimate of statistical molecular mass of polymeric material used particularly for PVC.
Is polyvinyl chloride A plastic?
Over the past few decades, Polyvinyl Chloride (PVC) plastic, commonly known as “vinyl,” has become one of the most widely-used types of plastics. PVC contaminates humans and the environment throughout its lifecycle during its production, use and disposal.
Where is PVC manufactured?
