Kuraray EXCEVAL™

EXCEVAL is a water-soluble, modified polyvinyl alcohol (PVOH) polymer developed by Kuraray. Combining Kuraray Poval and ethylene vinyl alcohol (a building block of Kuraray EVAL), EXCEVAL shares many of the properties of EVAL and Poval, including EVAL’s gas barrier characteristic and Poval’s coat-ability. The unique qualities of EXCEVAL invite a wide range of potential applications.
