Description
Polyvinyl Alcohol Product Overview
Polyvinyl alcohol is made by hydrolyzing polyvinyl acetate. It is supplied as white granules or powder and is classified by two key properties: the degree of hydrolysis (partially hydrolyzed, about 87–89%, or fully hydrolyzed, about 98–99%) and the viscosity of a 4% solution, which reflects the molecular weight. These two values determine solubility, strength and film properties.
PVA forms strong, flexible and oxygen-barrier films and has excellent adhesion to cellulose. It is used for warp sizing in textiles, in paper coatings and binders, in wood and paper adhesives, and as a protective colloid in the emulsion polymerization of vinyl acetate. Water-soluble PVA films are used for detergent pods and agrochemical packaging.
In construction, PVA is added to mortars, tile adhesives and gypsum products to improve adhesion and flexibility. For thickening applications, it is sometimes combined with or compared to cellulose derivatives such as Sodium CMC.

⚠️ Safety & Handling: Not classified as hazardous under GHS. Fine dust may form explosive mixtures with air and may irritate the eyes, so avoid creating dust and keep away from ignition sources. Store in tightly closed bags in a cool, dry place. Always consult the Safety Data Sheet (SDS) for full classification and handling instructions.
Frequently Asked Questions
Which PVA grade do I need?
Fully hydrolyzed grades give higher water resistance and strength, partially hydrolyzed grades dissolve more easily in cold water. Tell us your application and we will suggest suitable grades.
How do I dissolve polyvinyl alcohol?
Disperse it in cold water under stirring, then heat to about 85–95°C until fully dissolved. Fully hydrolyzed grades need the higher end of this range.
How can I get a price and documents?
Prices depend on quantity, packaging and destination. Contact us with your required volume to receive a quotation together with the CoA and SDS.
