Polyvinyl chloride

Polyvinyl chloride (Polyvinyl chloride), abbreviated as PVC, is the world’s third largest production of synthetic polymer plastics (after polyethylene and polypropylene ), the annual production of about 40 million tons of PVC. PVC is vinyl chloride monomer (VCM) in peroxide, azo compounds, and other initiators, or under the action of light, heat, and other polymers in accordance with free radical polymerization reaction mechanism. Polymer. Vinyl chloride homopolymers and vinyl chloride copolymers are collectively referred to as vinyl chloride resins.

PVC was once the world’s largest general-purpose plastic in terms of production volume, and is used in a wide range of applications. There are two types of PVC, rigid (sometimes abbreviated as RPVC) and soft. Rigid PVC is used for building pipes, doors and windows. It is also used to make plastic bottles, packaging, and bank or loyalty cards. Adding plasticizers makes PVC softer and more flexible. It is used in pipes, cable insulation, flooring, signs, phonograph records, inflatable products and rubber substitutes.
