Product overview
Vinyl Acetate Monomer (VAM), also known as Acetic Acid Vinyl Ester or Ethenyl Acetate, with the molecular formula C₄H₆O₂ and CAS number 108-05-4, is a clear, colorless, flammable liquid with a characteristic sweet, pleasant odor . As one of the most important industrial monomers globally, VAM is produced primarily through the reaction of ethylene with acetic acid in the presence of a palladium catalyst (ethylene process) or via acetylene with acetic acid . With a boiling point of 72°C and a flash point of -8°C, it is classified as a highly flammable liquid (UN 1301, Class 3, Packing Group II) . Due to its high reactivity and tendency to polymerize, commercial VAM is typically stabilized with hydroquinone (8-12 ppm) or similar inhibitors to prevent premature polymerization during storage and transport . As the essential building block for polyvinyl acetate (PVAc), polyvinyl alcohol (PVOH), ethylene-vinyl acetate (EVA), and EVOH, VAM is indispensable across adhesives, water-based paints, paper coatings, textile finishes, and photovoltaic solar encapsulant films .
