Polyvinyl Acetate(PVAC)


Polyvinyl Acetate (PVA or PVAc) is a thermoplastic polymer with a chemical formula of (C4 H6 O2)n It is normally manufactured by the free radical polymerization of vinyl acetate. PVAc is used in the production of gum base as an elastomer. This provides elasticity or bounce to the gum base. As other synthetic elastomers, it has been one of the commercially produced synthetic materials that is a substitute for natural materials historically used in the production of gum base.
