The PVC molecular weight of industrial production is generally in the range of 50,000 ~ 110,000, with a large polydispersity, the molecular weight increases with the reduction of polymerization temperature, no fixed melting point,80~85 began to soften,130 into viscoelastic state,160~180 began to change into viscous flow state; It has good mechanical properties, tensile strength of about 60MPa, impact strength of 5~10kJ/m2; With excellent dielectric properties, PVC used to be the world's largest production of general plastic, widely used in building materials, industrial products, daily necessities, floor leather, floor brick, artificial leather, pipe, wire, cable, packaging film bottle, foaming material, sealing material, fiber and other aspects are widely used.
