What is Vinyl acetate monomer CAS No 108-05-4 ?
VAM Vinyl Acetate Monomer CAS 108-05-4 is a high-reactivity industrial monomer with a typical purity of ≥99.5%, widely recognized as the core building block for vinyl-based polymers. As a colorless transparent liquid, its defining feature is the reactive vinyl group, which enables efficient free-radical polymerization with itself or comonomers.

Vinyl acetate monomer - Uses
Adhesives and sealants industry:
Monomer Vinyl Acetate VAM is the primary raw material used to produce polyvinyl acetate (PVA), a substance employed in the manufacture of white wood glue, paper adhesives, and packaging sealants. It also contributes to ethylene-vinyl acetate (EVA) hot-melt adhesives, which are widely used in packaging and the footwear industry.
Coatings and paints sector:
PVA and VAE emulsions derived from VAM chemical are key components of water-based interior and exterior wall paints, architectural coatings and paper coatings, improving printability and surface strength.
Packaging industry:
VAM-derived polymers play a critical role here. Polyvinyl alcohol (PVOH) is used to make water-soluble packaging films for detergent pods and agricultural chemicals. Ethylene vinyl alcohol (EVOH), a vinyl acetate monomer copolymer, is a high-performance gas barrier material used in co-extruded films for food preservation as it prevents oxygen and carbon dioxide from permeating the film. EVA is also used for flexible packaging films and extrusion coatings.
Textile and paper processing:
PVA acts as a textile warp sizing agent to protect yarns during weaving and PVOH is used in paper surface sizing to enhance strength and water resistance.
In the electrical and construction sectors:
Polyvinyl acetals derived from VAM are employed in magnetic wire insulation and safety glass interlayers. Due to its flexibility and insulation properties, EVA is employed in wire and cable jacketing, while VAE emulsions are used in tile adhesives and construction sealants.
Specialty applications:
VAM (CAS 108-05-4) copolymers are used in pressure-sensitive adhesives for tapes, as well as in foam materials for sports equipment and shoe soles.
