Kuraray Poval™ 8-88

1 of 147 products in this brand
KURARAY POVAL™ 8-88 by Kuraray is a polyvinyl alcohol (PVOH) having varying degree of polymerization and hydrolysis. It is a water-soluble polymer manufactured by alcoholysis of polyvinyl acetate. It is notable for its good bonding strength and pigment binding capacity because PVAs have such good cohesion and good adhesion to fibers, fillers as well as pigments. KURARAY POVAL™ 8-88 is used in a similar manner as natural products such as casein as well as starch and its degraded derivatives (for example dextrin) as raw material for the production of aqueous adhesive solution. In comparison to dextrin and casein it has the advantage of a more uniform chemical structure and greater adhesion, being obtained with minimum raw material requirements. It features water-solubility, excellent film forming characteristics, high tensile strength and elasticity, as well as resistance against organic solvents and dispersing power. For the modification of aqueous adhesives its aqueous solution can be added to polymer emulsions already stabilized with polyvinyl alcohol which affects the extension of the open time, increase of the setting speed and influence on the rheology. It is biodegradable and recyclable. KURARAY POVAL™ 8-88 is used in producing silicon base paper that are further used as release paper for PSA labels and also in remoistenable adhesives which are employed mainly in the paper processing industry, films applications.
