Polyvinyl Alcohol&Polyvinyl Acetate
Polyvinyl alcohol and polyvinyl acetate are both shortened to PVA, but to be precise, the abbreviation for polyvinyl acetate is PVAc.
PVAc is formed by polymerization of vinyl acetate in the presence of acetic acid and is mainly used as a coating, adhesive, paper, gum base and fabric finishing agent.
PVAc was first discovered by the German scientist “Dr. Fritz Klatte” in 1912. Since then it has been widely used in binding materials because it is suitable as a binder for hole-like materials such as wood and paper. In addition to its previous use as polyvinyl acetate glue, it is also used in paper and textiles to help produce a PVA coating to add a smooth surface. PVA is often used to produce latex layers, which can form a hard outer layer and supporting film. In addition, it is also widely used in the production of polyvinyl acetate adhesive.
PVAc is the raw material of PVA, which is one of the main uses of PVAc.
