Product Description
Exceval™ is the trademark of Kuraray's novel water soluble polymer, specially designed for "high water resistance". It is commonly known that fully hydrolyzed polyvinyl alcohol shows higher water resistance based on the higher crystallinity than that of partially hydrolyzed polyvinyl alcohol, but "viscosity stability" is the critical problem. Exceval™ achieves the compatibility of both performances, "high water resistance" and "viscosity stability" based on Kuraray's accumulated technology.
