Polyvinyl chloride, abbreviated as PVC, is a polymer formed by the free radical polymerization mechanism of vinyl chloride monomer (VCM). Vinyl chloride homopolymers and vinyl chloride copolymers are collectively referred to as vinyl chloride resins.

The molecular weight of PVC produced in industrial production is generally in the range of 50000 to 110000, with a high degree of polydispersity. The molecular weight increases with the decrease of polymerization temperature, without a fixed melting point. It begins to soften at 80-85 ℃, becomes viscoelastic at 130 ℃, and transitions to a viscous flow state at 160-180 ℃; Has good mechanical properties, with a tensile strength of about 60MPa and an impact strength of 5-10kJ/m2; Has excellent dielectric properties.

PVC is one of the most widely used general-purpose plastics in the world, with a wide range of applications. It is widely used in building materials, industrial products, daily necessities, floor leather, floor tiles, artificial leather, pipes, wires and cables, packaging films, bottles, foam materials, sealing materials, fibers, and other fields.
