POLYVINYL ALCOHOL KURARAY POVAL™
KURARAY POVAL™ – champion in versatility
The main uses of KURARAY POVAL™ are in the paper, adhesive, textile and construction industries, as well as in ceramics, packaging and electronics. The physical and chemical properties make PVOH very versatile. It features water-solubility, excellent film forming characteristics, high tensile strength and elasticity, as well as resistance against organic solvents and dispersing power.
Reactivity of numerous hydroxyl groups with substances such as aldehydes and other reactive compounds expand the range even wider.
KURARAY POVAL™ meets all requirements – from low to high viscosity, partially to fully saponified.
With more than 70 years of experience and extensive production and application expertise, we can tailor the properties of our polymers precisely to our customers specification.
Benefit from the wide range of high-performance materials from Kuraray, a world-leading PVA producer, that meet the highest standards for your individual applications.
Excellent crosslinking for paper, textiles and adhesives
KURARAY POVAL™ K grades have very good crosslinking properties and excellent solubility in water – for applications in the paper, packaging and textile industries and in emulsions for adhesives.
Excellent bonding power for high-performance coatings
Integrated silanol groups give KURARAY POVAL™ R grades outstanding bonding power – so coatings have excellent adhesion to inorganic materials such as glass, aluminum and steel.
Low methanol content for well-tolerated cosmetics
Thanks to their low methanol content, KURARAY POVAL™ LV grades have no adverse health impacts and a good environmental profile – for cosmetics and personal-care products that are kinder to the skin.
Low viscosity and water-soluble for higher quality PVC
KURARAY POVAL™ L grades have low hydrolysis and are completely soluble in water. The unique viscosity of these PVOH polymers makes them ideal as protective colloids in PVC suspension polymerization.
Low-Hydrolyzed KURARAY POVAL™ LM Grades
In addition, Kuraray markets low-hydrolyzed KURARAY POVAL™ LM grades. Their low glass transition temperature and excellent dispersing properties make them ideal as strong secondary protective colloids for PVC production.
KURARAY POVAL™ KX grades – High Molecular Weight PVOH
KURARAY POVAL™ 200-88 KX, KURARAY POVAL™ 200-88 KX SB, and KURARAY POVAL™ 105-88 KX SB offer superior shear thinning behavior and higher extensional viscosity, making them ideal for applications such as adhesives, tissue production, and paper coating.
