Description
Vinyl acetate (CAS 108-05-4, EC 203-545-4), also known as VAC, Acetoxyethene, and acetate de vinyle, is a reactive monomer belonging to the ester family. It carries no E-code designation and is classified under HS code 29153200 for customs and trade purposes.
In polymer manufacturing, vinyl acetate undergoes free-radical polymerization to form polyvinyl acetate (PVAc), the base resin for adhesives, paints, and coatings. In food and fragrance applications, it functions as a flavorant and fragrance component, where its ester structure contributes characteristic fruity notes at controlled concentrations.
Vinyl acetate is supplied as a stabilized liquid monomer in compliance with REACH registration requirements. It is available in standard industrial drum and IBC formats suited to polymer and formulation production environments. Procurement teams should confirm inhibitor levels and storage specifications when sourcing for polymerization applications.
