Partially Hydrolyzed Polyvinyl Alcohol (PVA) is a synthetic polymer derived through partial hydrolysis of polyvinyl acetate, typically with a hydrolysis degree ranging from 80% to 90%. 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.
