Polyvinyl chloride (PVC) is the initiator of vinyl chloride monomer (VCM) in peroxide, azo compounds, etc.Or under the action of light and heat according to the free radical polymerization reaction mechanism of polymer.The homopolymer of vinyl chloride and the copolymer of vinyl chloride are called vinyl chloride resins.

PVC for amorphous structure of white powder, branched degree is small, relative density 1.4, glass transition temperature of 77 ~ 90 ℃, 170 ℃ or so began to decompose, poor stability to heat and light, in more than 100 ℃ or the sun for a long time, will decompose and produce hydrogen chloride, and further automatic catalytic decomposition, cause discoloration, physical and mechanical properties also fell rapidly,In practice, stabilizers must be added to improve thermal and light stability.

The molecular weight of PVC produced by industry is generally in the range of 50,000 ~ 110,000, with large polydispersity, and the molecular weight increases with the reduction of polymerization temperature;No fixed melting point, 80~85℃ to soften, 130℃ to viscoelastic state, 160~180℃ to change into viscous flow state;It has good mechanical properties, tensile strength of about 60MPa, impact strength of 5~10kJ/m2;Excellent dielectric properties.

PVC used to be the world’s largest production of general-purpose plastics, widely used.It is widely used in building materials, industrial products, daily necessities, floor leather, floor tile, artificial leather, pipe, wire and cable, packaging film, bottle, foaming material, sealing material, fiber and so on.
