PVC resin powder has excellent flame retardancy, abrasion resistance, chemical corrosion resistance, comprehensive mechanical properties, product transparency, electrical insulation and relatively easy processing. Therefore, it is widely used in the production of profiles, special profiles, pipes and fittings, plates, sheets, wire and cable sheaths, hard or soft tubes, blood transfusion equipment and films, etc. It is widely used in industry, construction, agriculture, electric power, medical equipment, daily life, packaging and other fields.

There are many types of PVC resin powder. According to different application areas, PVC can be divided into: general-purpose PVC resin, high-polymerization PVC resin, and cross-linked PVC resin. General-purpose PVC resin is formed by the polymerization of vinyl chloride monomer under the action of an initiator; high-polymerization PVC resin refers to a resin polymerized by adding a chain extender to the vinyl chloride monomer polymerization system; cross-linked PVC resin is A resin polymerized by adding a cross-linking agent containing diene and polyene to the vinyl chloride monomer polymerization system.
