    PVC is one of the five main plastics materials after PE. Widely used in the production of transparent

    sheets, pipes, fittings, plates, doors and windows, profiles, films, floors, artificial leather, packaging

    materials, electrical insulation materials, cable sheaths, medical equipment and so on.

    PVC is synthesized from vinyl chloride through free radical polymerization. The polymerization process

    consists of suspension polymerization, emulsion polymerization and bulk polymerization. The suspension

    polymerization method accounts for about 80% of the total output of PVC.

    PVC can be divided into calcium carbide method and ethylene method according to the source of

    vinyl chloride monomer.

    According to the different production methods, pure PVC powder can be divided into general PVC resin,

    high degree of polymerization PVC resin and cross-linked PVC resin.


    Widely used


    Easy processing and shaping

    Flame retardant

    Strong acid resistance, high alkali chemical

    Good electrical insulation


    The stability of light and heat is poor.

    Poor toughness, brittleness, etc.

    It needs to be modified by chemical additives
