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