Polyvinyl chloride
Polyvinyl chloride (alternatively: poly(vinyl chloride),colloquial: vinyl or polyvinyl; abbreviated: PVC) is the world’s third-most widely produced synthetic polymer of plastic (after polyethylene and polypropylene). About 40 million tons of PVC are produced each year.
PVC comes in rigid (sometimes abbreviated as RPVC) and flexible forms. Rigid PVC is used in construction for pipes, doors and windows. It is also used in making plastic bottles, packaging, and bank or membership cards. Adding plasticizers makes PVC softer and more flexible. It is used in plumbing, electrical cable insulation, flooring, signage, phonograph records, inflatable products, and in rubber substitutes.With cotton or linen, it is used in the production of canvas.
