The Kuraray group is committed to developing new fields of business using pioneering technology that improves the environment and enhances the quality of life through the world.

Kuraray America INC, is a global leader in specialty chemical, Fiber and resin production. With top-of0the-line research and production facilities located in Houston, Texas and a vast network of supply from around the world, Kuraray leads the industry in speciality products.

Kuraray was founded in 1926 for the purpose of commercializing synthetic rayon, which was a cutting-edge technology at the time. Following the Second World War, in 1950 we were first in the world to commercialize polyvinyl alcohol (PVA) fiber, under the brand name KURALON™. It was the first synthetic fiber invented in Japan, and led the early phase of Japan’s synthetic fiber industry.

Kuraray polyvinyl alcohol (PVOH) resins, KURARAY POVAL™ and Elvanol™ are diverse in their applications as well as processing.

About Elvanol™ – link

Kuraray manufactures several types of Elvanol™ products which are available as fully hydrolyzed or as a copolymer. The fully hydrolyzed grades contain few, if any, residual acetate groups; while partially hydrolyzed grades retain some of the residual acetate groups. The partially hydrolyzed grades dissolve in water at room temperature; fully hydrolyzed grades dissolve in hot (85°C) water, and remain in solution when cooled to room temperature.
The copolymer grades, developed specifically for warp sizing in the textile and paper industry, offer a unique balance of properties to Kuraray’s Elvanol™ customers.
