    GNF Polyvinyl chloride (PVC) CAS 9002-86-2
    Introduction PVC resin, short for Polyvinyl Chloride resin, is an important organic synthetic material. PVC resin is a polar non - crystalline high - polymer with relatively strong forces between molecules, making it a hard and brittle material with lower impact strength. Its chemical structural formula is (CH₂ - CHCl)ₙ. It is usually in the form of white powder, non - toxic and odorless. PVC is produced by the polymerization of vinyl chloride monomer (VCM). There are two main polymerization techniques: suspension PVC and emulsion PVC. It is the world's third - most widely produced synthetic plastic polymer, after polyethylene and polypropylene. The products made from PVC resin have good physical and chemical properties. It is durable, light, strong, and fire - resistant, with excellent insulating properties and low permeability. PVC is widely used in various fields such as industry, construction, agriculture, daily life, packaging, electricity, and public utilities. In the building and construction industry, it is used for pipes, windows, doors, etc.; in the healthcare industry, it is used for blood bags and tubing; in the electronics industry, it is used for wire and cable insulation.
