VynoKlear

Polymer Name: Polyvinyl Chloride (PVC)
Processing Methods: Extrusion, Injection Molding, Calendering
End Uses: Medical Packaging, Cables, Flooring

VynoKlear is a high molecular weight vinyl chloride homopolymer produced by a suspension process with no addition of antioxidant. After mixing with appropriate additives, VynoKlear is suitable for extrusion, calendering or injection molding of semirigid and flexible PVC. Its superior porosity, compatibility, and transparency make it ideal for clear medical products, waterproofing membranes, and innovative flexible consumer goods and cables.

Kuraray Poval™ 8-88

Polymer Name: Polyvinyl Alcohol (PVOH)
Functions: Resin, Binder, Coupling Agent
Chemical Family: Polyvinyl Alcohols & Esters, Vinyls, Vinylics & Vinyl Derivatives

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.
