- What is PVC?
Polyvinyl chloride, referred to as PVC (Polyvinyl chloride) in English, is an initiator of vinyl chloride monomer (VCM) in peroxides, azo compounds and other initiators; or by the mechanism of free radical polymerization under the action of light and heat polymerized polymer. Vinyl chloride homopolymers and vinyl chloride copolymers are collectively referred to as vinyl chloride resins.
The molecular weight of industrially produced PVC is generally in the range of 50,000 to 110,000, with a large polydispersity, and the molecular weight increases with the decrease of the polymerization temperature; there is no fixed melting point, it begins to soften at 80-85 °C, and becomes viscoelastic at 130 °C , 160 ~ 180 ℃ began to transform into a viscous flow state; good mechanical properties, tensile strength of about 60MPa, impact strength of 5 ~ 10kJ/m2; excellent dielectric properties.
PVC was once the largest general-purpose plastic in the world, 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, foam materials, sealing materials, fibers, etc.
