Polyvinyl alcohol (PVA) powder is a water‑soluble synthetic polymer with a wide range of applications across diverse industries. Known for its film‑forming, emulsifying, and adhesive properties, PVA powder has become a cornerstone material in sectors as varied as packaging, textiles, construction, and biomedical science. PVA powder is produced by hydrolyzing polyvinyl acetate PVA Pulver under alkaline conditions to replace acetate groups with hydroxyl (–OH) groups. The degree of hydrolysis—ranging from 80% to over 99%—and the polymer’s molecular weight determine key properties such as solubility, viscosity, and mechanical strength. Fully hydrolyzed grades (95–99+%) tend to exhibit higher crystallinity, superior film strength, and lower solubility at room temperature, while partially hydrolyzed grades dissolve more readily in cold water. PVA powder is generally non‑hazardous, but fine particles can create dust that may irritate eyes or respiratory tract. Adequate ventilation and personal protective equipment (PPE) such as masks and goggles are recommended during handling. The powder should be stored in a cool, dry place, protected from humidity to prevent premature hydrolysis and caking.
