Basic property ofKuraray Poval™ andExceval™ for paper
applications
Kuraray has the widest range of
PVOH grades available. Conventional Kuraray Poval™ grades aremainly characterized by theirmolecular weight (measured assolution viscosity) and degree ofhydrolysis.

Bright ideas forpaper applications
In graphical paper grades our products play an important roleas carriers for optical brighteners in line with the trend toward enhanced paper whiteness. Simultaneously, they serveas thickening and water retention aid for better productivity.
Owing to the insolubility of polyvinyl alcohol in non aqueous
solvents, Kuraray Poval™ and Exceval™ grades are ideal forforming barrier coatings, e. g. barrier for silicone oil, grease,oil, oxygen or against migration of mineral oil. In other sectors
Kuraray Poval™ are utilized as powerful binders to produce
matt, glossy or high speed industrial inkjet papers. Also Kuraray Poval™ and Exceval™ are used as dispersing agent, binder
and top coating in thermal papers.

Exceval™ is Ethylene modified PVOH, which enhances
water resistance and film
forming performance
beyond that of conventional
PVOH resins for coatedpapers. Additionally, Kuraray offers various otherfunctionally modified PVOH
grades which which meetthe requirements of eachspecial paper application.
