3. Application
used in the production of polyvinyl alcohol, coatings and adhesives.It is an important organic chemical material.Vinyl acetate by its polymerization or copolymerization with other monomers,mainly use for the production of polyvinyl acetate (PVAc),polyvinyl alcohol (PVA),vinyl acetate - ethylene copolymer emulsion (VAE) or vinyl acetate copolymer (EVA) resin,vinyl chloride copolymer (EVC), acetal resins such as derivatives. These derivatives usage is very extensive and can be used for bonding agent, and glue pharmaceutical of paper or fabric, coating, ink, leather processing, fibre processing, emulsifier, water soluble film, soil conditioner,.VAM is an important synthetic material monomer. with the progress of science and technology, other downstream products and new applications are still in constant development.
Vinyl acetate is used to make other industrial chemicals.These chemicals are used mainly to make glues for the packaging and building industries.They are also used to make paints,textiles,and paper.Vinyl acetate is also used as a coating in plastic films for food packaging and as a modifier of food starch.
