【 Product of VAM Plant 】
  Vinyl Acetate Monomer ( VAM ) is an active, colorless, and liquid phase chemical, produced by the vapor phase reaction of Ethylene, Acetic Acid and Oxygen over a catalyst. Stabilized with hydroquinone inhibitor for storage.
The main applications are as follows:For manufacturing following products:
  • Polyvinyl Acetate
    The emulsion polymer is used as adhesive for paper, wood, non-woven fabrics, rug backing or used as material of paint. The polymer prepared by solution polymerization is used as a base material of chewing gum.
  • Polyvinyl Alcohol
    Used as textile warp and yarn size, laminating adhesive, emulsifying agent and films.
  • Vinyl Acetate-Ethylene Copolymer
    High ethylene content copolymer EVA resin is used as packaging film, blow-molded and hot melt products. Low ethylene content copolymer EVA emulsion is used as adhesive, paint and paper coating.
  • Vinyl Acetate-Vinyl Chloride Copolymer
    Used as LP records and plastic floor tile.
  • Ethylene-Vinyl Acetate- Vinyl Chloride Terpolymer
    Used as adhensive with its excellent water resistance and fire retardant characteristics.
  • Polyvinyl Butyral
    Used as interlayer of safety glass.
