Audited Supplier Polyvinyl chloride (PVC) is a polymer of vinyl chloride monomer (VCM) polymerized by peroxide, azo compounds and other initiators or by free radical polymerization reaction mechanism under the action of light and heat. Vinyl chloride homopolymer and vinyl chloride copolymer are called vinyl chloride resin.
PVC is also the world's third-most widely produced synthetic polymer of plastic.
It is used in making plastic bottles, non-food packaging, food-covering sheets and plastic cards (such as bank or membership cards).
Roughly half of the world's PVC resin manufactured annually is used for producing pipes for municipal and industrial applications.
PVC is commonly used as the insulation on electrical cables such as teck; PVC used for this purpose needs to be plasticized. Flexible PVC coated wire and cable for electrical use has traditionally been stabilized with lead, but these are being replaced with calcium-zinc based systems.
PVC is strong but lightweight plastic used in construction. It is made softer and more flexible by the addition of plasticizers.
