Polyvinyl alcohol PVA 1788 2488
Polyvinyl alcohol (PVA), a colourless, water-soluble synthetic resin employed principally in the treating of textiles and paper.
PVA is used in sizing agents that give greater strength to textile yarns and make paper more resistant to oils and greases. It is also employed as a component of adhesives and emulsifiers, as a water-soluble protective film, and as a starting material for the preparation of other resins. By reaction with butyraldehyde (CH3CH2CH2CHO) and formaldehyde (CH2O), PVA can be made into the resins polyvinyl butyral (PVB) and polyvinyl formal (PVF). PVB, a tough, clear, adhesive, and water-resistant plastic film, is widely used in laminated safety glass, primarily for automobiles. PVF is used in wire insulation.
