PVC is Polyvinyl Chloride (PVC), an initiator of vinyl chloride monomers (VCM) in peroxides, azo compounds, etc.; or by radical polymerization under the action of light and heat. The polymer formed by the reaction mechanism. Chloroethylene homopolymers and vinyl chloride copolymers are collectively referred to as vinyl chloride resins. Its material is a non-crystalline material. In practice, PVC materials often include stabilizers, lubricants, auxiliary processing agents, colorants, impact modifiers, and other additives. With non-flammability, high strength, weather resistance and excellent geometric stability. PVC is very resistant to oxidants, reducing agents and strong acids. However, it can be corroded by concentrated oxidizing acids such as concentrated sulfuric acid, concentrated nitric acid, and is not suitable for applications in contact with aromatic hydrocarbons and chlorinated hydrocarbons.
