Chemical Description

  • Vinyl acetate (VAM), also known as acetic acid vinyl ester or ethenyl acetate, is a colorless liquid with a pungent odor.
  • It is an organic compound with the chemical formula CH3COOCH=CH2.
  • VAM is primarily used as a monomer in the production of polyvinyl acetate (PVA), which is a widely used adhesive and binder.
  • Additionally, VAM serves as a precursor in the manufacture of other polymers such as polyvinyl alcohol (PVOH), ethylene-vinyl acetate (EVA), and vinyl acetate-ethylene (VAE) copolymers.
  • One of the major applications of VAM is in the production of emulsion-based polymers used in paints, coatings, adhesives, and textiles.
  • In the adhesives industry, VAM-based polymers provide excellent adhesion to various substrates, making them suitable for applications in woodworking, packaging, and construction.
  • VAM is also utilized in the production of water-based coatings and paints, where it contributes to film formation, adhesion, and flexibility.
  • Moreover, VAM-based polymers find applications in the manufacture of paper coatings, textile finishes, and as binders in nonwoven fabrics.
  • The low glass transition temperature (Tg) of VAM-based polymers makes them suitable for applications requiring flexibility and softness, such as in flexible packaging films and synthetic leather.
  • VAM is produced industrially by the reaction of acetic acid with ethylene in the presence of a catalyst, typically a palladium or rhodium complex.
  • It is important to ensure high purity and low levels of impurities in VAM to maintain product quality and performance in various applications.
  • The chemical stability and reactivity of VAM make it a versatile building block for the synthesis of a wide range of polymeric materials used in diverse industries.
  • Vinyl acetate monomer (VAM) is a colorless liquid, immiscible or slightly soluble in water. VAM is a flammable liquid.
  • VAM has a sweet, fruity smell (in small quantities), with sharp, irritating odor at higher levels. 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.
  • Vinyl acetate is used to produce polyvinyl acetate emulsions and resins. Very small residual levels of vinyl acetate have been found present in products manufactured using VAM, such as molded plastic items, adhesives, paints, food packaging containers, and hairspray.
