Description
[Kuraray-Poval (formerly DuPont)] A registered trademark for a series of Polyvinyl alcohol emulsions. Elvanol® products are prepared in water solutions and are compatible with Starch and Carboxymethyl cellulose. When dried, they produce a water-resistant coating. They are used commercially as adhesives, emulsifiers, textile finishing materials, photosensitive coatings, and binders in paper products.

At tempoeratures above the “conditions to avoid” temperature, thermal decomposition of the resin becomes rapid. Hazardous decomposition products: carbon monoxide, Organic acids, Aldehydes, Alcohols, Sodium oxides. (from SDS)
Environmental Risks
Biodegradable and recyclable [1]
Physical and Chemical Properties
Elvanol® 71-30: fully hydrolyzed, viscosity=medium, used as a replacement for starch and as a water and grease resistant sizing, coating, or adhesive
