Polyvinyl Alcohol (PVA) Introduction
- Introduction:
PVA resin is a kind of heavy polymer. It is usually white or slight yellow floccules, flake, granular or powdery in appearance.
PVA is non-toxic, insipid and non-polluting. PVA is a kind of water-soluble resin with good chemical stability. It also has good adhesion, film-forming ability, insulation, oil resistance, abrasion resistance and gas barrier properties, and has typical chemical properties of polyols and can make esterification, etherification, acetalization reactions.

- Usage:
Add water at room temperature in the dissolving tank. Start the agitator, slowly add calculated amount of PVA into the tank. Keep PVA swelling in the water at room temperature for about 30min, and then raise the temperature of the PVA aqueous solution, when the temperature reaches 90-95℃, keep the temperature for 1-2hours. PVA can completely dissolve.
