Polyvinyl Alcohol (PVA) is a water-soluble synthetic polymer with excellent film-forming, adhesive, and emulsifying properties.
It is widely used in textiles, paper coatings, adhesives, and construction materials due to its biodegradability and chemical resistance.
Water-Soluble – Dissolves in cold/hot water for easy application
High Tensile Strength – Forms strong, flexible films
Adhesion & Binding – Enhances cohesion in coatings and adhesives
Chemical Resistance – Stable against oils, greases, and solvents
Biodegradable – Eco-friendly alternative to synthetic polymers

1. Fully Hydrolyzed (98-99.9%) - High strength, chemical resistant (films, adhesives)
2. Partially Hydrolyzed (87-89%) - Fast-dissolving (textiles, paper)
3. Low Viscosity (5-15mPa·s) - Easy handling (cosmetics, coatings)
4. High Viscosity (30-65mPa·s) - Strong binding (cement, thick adhesives)
5. Modified Grades - Custom properties (specialty applications)
Water-based glues, remoistenable adhesives
Warp sizing, fiber reinforcement
Barrier films, release papers
Cement additives, tile adhesives
Biodegradable films
