What is Polyvinyl Acetate (PVA) glue made up of?

How is PVA glue made?

PVA is polyvinyl acetate. It belongs to polyvinyl esters family with the general formula [RCOOHCHCH2] and molecular formula (C4H6O2)2. It is a type of thermoplastic which becomes bendable, or mouldable, at a specific temperature and solidifies after cooling. Moreover, thermoplastics have high molecular weight making it a good adhesive usage.

Molecules are connected with each other through intermolecular forces and on heating, this molecular bonding becomes weaker – by changing its state to a liquid.

Thermoplastics may be reshaped and used to produce parts by different techniques: molding, injection, calendering and extrusion.
