VAC is one of fifty chemical materials which output is the largest in the world. It can be used in production of PVAC emulsion.Also it can bepolymerized with other matter and then used as materials in coating, adhesion agent, membrane. It is widely used in textiles, building, medicine, optics and pa-per processing etc. Vinyl Acetate is mainly used as a monomer in the production of Polyvinyl Acetate and Polyvinyl Alcohol. Vinyl Acetate is also used as a raw material in the production of other chemicals, in adhesives, water-based paints, nonwoven textile fibers, textile sizings and finishes, paper coatings, inks, films, and lacquers. Vinyl Acetate Monomer VAM is an essential chemical building block used in a wide variety of industrial and consumer products. VAM is a key ingredient in emulsion polymers, resins, and intermediates used in paints, adhesives, coatings, textiles, wire and cable polyethylene compounds, laminated safety glass, packaging, automotive plastic fuel tanks, and acrylic fibers.
