PVC (polyvinyl chloride) is a kind of initiator of vinyl chloride monomer (VCM) such as peroxide and azo compound, or a polymer which is polymerized by free radical polymerization under the action of light and heat. Vinyl chloride homopolymer and vinyl chloride copolymer are collectively referred to as vinyl chloride resin. The material is a non crystalline material. Stabilizer, lubricant, auxiliary processing agent, pigment, impact resistance agent and other additives are often added to PVC materials in practical use. It has no flammability, high strength, weather resistance and excellent geometric stability. PVC has strong resistance to oxidants, reducing agents and strong acids.
