Kuraray Poval®, Mowiol®, Mowiflex®

Kuraray’s polyvinyl alcohol (PVOH) resins are diverse in their applications as well as processing. Known for their excellent film formation, emulsifying power, and adhesion to the substrate, Kuraray PVOH resins can be used throughout the industry. Kuraray PVOH resins are produced by saponification of polyvinyl acetate, specifically using a continuous process. With stable quality, low ash, and VOC contents, Kuraray PVOH resins set a high standard in today’s market.
