Introduction of PVC Material

Polyvinyl chloride (Polyvinyl chloride), abbreviated as PVC in English, is a polymer of vinyl chloride monomer (VCM) polymerized by peroxides, azo compounds and other initiators or under the action of light and heat according to the free radical polymerization reaction mechanism. . Vinyl chloride homopolymer and vinyl chloride copolymer are collectively referred to as vinyl chloride resin.
PVC is a white powder with an amorphous structure, with a small degree of branching. The glass transition temperature is 77~90℃, and it starts to decompose around 170℃[1]. It has poor stability to light and heat. It is above 100℃ or exposed to long-term sunlight. , It will decompose to produce hydrogen chloride, which will be further autocatalyzed and decomposed, causing discoloration, and the physical and mechanical properties will also decline rapidly. In practical applications, stabilizers must be added to improve the stability to heat and light.

PVC Material used to be the world's largest production of general-purpose plastics, and it is widely used. It is widely used in building materials, industrial products, daily necessities, floor leather, floor tiles, artificial leather, pipes, wires and cables, packaging films, bottles, foaming materials, sealing materials, fibers, etc.
