Polyvinyl acetate is a component of a widely used glue type, commonly referred to as wood glue , white glue, carpenter's glue, school glue, Elmer's glue (in the US), or PVA glue.” WebPoly (vinyl acetate), or PVA for short, is one of those low-profile behind-the-scenes polymers. It isn't blatantly obvious where it's found, as is the case with polyethylene or polystyrene. PVA likes to hide. But it's everywhere, if you're willing to look for it. It's a polymer that rewards one who is willing to look beyond the surface.
