Polyvinyl chloride (Poly Vinyl Chloride, PVC).
PVC is a polymer of vinyl chloride monomer (VCM) in initiators such as peroxides and azo compounds; or polymerized by the mechanism of free radical polymerization under the action of light and heat. Vinyl chloride homopolymers and vinyl chloride copolymers are collectively referred to as vinyl chloride resins.
The material is an amorphous material.
In the actual use of PVC materials, stabilizers, lubricants, auxiliary processing agents, colorants, anti-impact agents and other additives are often added. It has 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 and concentrated nitric acid, and it is not suitable for occasions in contact with aromatic hydrocarbons and chlorinated hydrocarbons.
