KURARAY POVAL ™ ( PVOH ) is an innovative material that makes products stronger and smarter. Through its application industries improves durability and improves performance.
Kuraray Poval™ is used for polyvinyl acetate emulsions, specifically in wood and paper adhesives. Kuraray’s specialty PVOH grades, like Exceval™, are used for water-resistant wood adhesives. Kuraray Poval™ can also be used in general-purpose adhesives such as textile, leather, wood, and porous ceramic surfaces.The partially hydrolyzed grades of Kuraray Poval™ are often selected for remoistening adhesives.As an emulsifier, Kuraray Poval™ and Exceval™ are widely used as a protective colloid in the emulsion process. They are often used during the polymerization of vinyl acetate and vinyl acetate copolymer systems (vinyl acetate/ethylene, vinyl acetate/acrylic ester, etc.) to form high-solids emulsions with stability and adhesive properties.
