PVC Resin DG-700

PVC Resin DG-700 Polyvinyl chloride (PVC), referred to as PVC in English, is a polymer formed by the polymerization of vinyl chloride monomer (VCM) according to the free radical polymerization mechanism. Vinyl chloride homopolymer and vinyl chloride copolymer are collectively referred to as vinyl chloride resin. The molecular weight of industrially produced PVC is generally in the range of 50,000 to 110,000, with large polydispersity. The molecular weight increases with the decrease of polymerization temperature. It has no fixed melting point. It begins to soften at 80-85°C, becomes viscoelastic at 130°C, and begins to change to viscous flow at 160-180°C. It has good mechanical properties, tensile strength of about 60MPa, impact strength of 5-10kJ/m2; it has excellent dielectric properties. PVC is one of the most produced general-purpose plastics in the world and 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.
