PRODUCT OVERVIEW

Product Description

PVA Series Polyvinyl Alcohol Powder is a white, water-soluble polymer widely used across textile, coating, adhesive, and emulsification applications. The material dissolves in hot water and combines useful film-forming, stabilizing, bonding, and sizing properties. It can be used as a warp-sizing agent, emulsifying stabilizer, wet-glue component, and raw material for water-soluble films. Its commercial quality is commonly evaluated through alcoholysis degree, sodium acetate content, volatile matter, pH, ash content, and viscosity.
