Partially Hydrolyzed Polyvinyl Alcohol (PVA) is a synthetic polymer derived through partial hydrolysis of polyvinyl acetate, typically with a hydrolysis degree ranging from 86 mole% to 89 mole%. This unique structure balances hydrophilic hydroxyl groups and residual hydrophobic acetate groups, making it versatile for applications requiring controlled water solubility and film-forming capabilities. It is widely used in adhesives, coatings, textile sizing, biodegradable films (e.g., detergent pods), and pharmaceutical binders due to its tunable dissolution properties and eco-friendly profile.
It dissolves in cold water. Produces films with enhanced flexibility and adhesion due to residual acetyl groups. Balances water absorption and moisture resistance, ideal for applications needing controlled solubility. Compatible with hydrophobic materials and organic solvents, broadening its usability.
