Kuraray Kuralon™ and Kuralon K-II™

Kuralon was the first synthetic fiber made in Japan, more than 60 years ago. Successfully commercialized by Kuraray, Kuralon is a world-class niche product that has been continually refined and improved over time to meet new applications and changes in demand—eventually leading to the development of a second generation, Kuralon K-II. Both Kuralon and Kuralon K-II are based on polyvinyl alcohol (PVOH) resin. These cutting-edge materials are used in many fields, including construction, specialty papers, and rubber reinforcement.
