GOLDENTREE PVA is a water-soluble white powder of polyvinyl alcohol. PVA (Polyvinyl Alcohol) , as a water-soluble resin dissolves easily in water, but solubility depends on the degree of polymerization, degree of hydrolysis and size of powder. The lower the degree of polymerization, the easier it dissolves in water. In general partially hydrolyzed grades are dissolved easily than fully hydrolyzed grades. Also, the dissolution rate of PVA (Polyvinyl Alcohol) depends on dissolution temperature and grain size of powder. The higher the temperature, the greater the rate of dissolution. The wispier the size is, the easier the rate of dissolution is. GOLDENTREE PVA is widely used in adhesive and ceramic binder, also used in cosmetics, emulsion stabilizer, construction, pharmacy and electronic industries.
GOLDENTREE PVA is divided into two main kinds namely 1788# and 2488# grades in according to the degree of polymerization. Every grade also is classified to 80 mesh (180micron) and 120 mesh (125micron) in according to grain size of powder.
