What Is PVA Glue? – Guide to Polyvinyl Acetate Adhesives
PVA glue is predominantly composed of aliphatic rubbery synthetic polymer. The chemical formula is (C4H6O2)n, so when it comes to production, PVA is typically produced by the free polymerization of radicals of synthetic vinyl acetate. When monomer molecules of vinyl acetate are immersed in water, they normally react, producing a milky …
