The usage of PVA glue ?

PVA is a colorless, usually nontoxic thermoplastic adhesive prepared by the polymerization of vinyl acetate. PVA was discovered in 1912 by Dr. Fritz Klatte in Germany.

The degree of polymerization of polyvinyl acetate is typically 100 to 5000, while its ester groups are sensitive to base hydrolysis and slowly convert PVAc into polyvinyl alcohol and acetic acid.

The glass transition temperature of polyvinyl acetate is between 30 and 45 °C depending on the molecular weight.

PVAc dispersions such as Elmer's Glue-All contain polyvinyl alcohol as a protective colloid. In alkaline conditions, boron compounds such as boric acid or borax cause the polyvinyl alcohol to cross-link, forming tackifying precipitates or toys, such as Slime and Flubber.

PVA sets when there’s good air circulation, and dries fastest at room temperature. You get the strongest seal when you clamp the pieces being glued. It’s quick drying with a very high bond strength.

The yellow exterior version of PVA is often called Carpenter’s Glue… but it’s still PVA. In fact, there is a bewildering array of specialist PVAs but the formula is much the same.

A number of microorganisms can degrade polyvinyl acetate. Most commonly, damage is caused by filamentous fungi—however algae, yeasts, lichens, and bacteria can also degrade polyvinyl acetate.
