WANWEI PVA0588

Wanwei PVA-0588 is an ultra-low viscosity polyvinyl alcohol (PVA) known for its excellent solubility, adhesive properties, and film-forming capabilities. With a degree of alcoholysis typically around 88% and a viscosity ranging from 4-6 mPa·s (4% aqueous solution, 20°C), it is widely used in adhesives, coatings, and specialized industrial applications. PVA-0588 is highly soluble in both hot and cold water, making it easy to handle and process. It forms transparent and flexible films, and its biodegradable and non-toxic nature makes it suitable for environmentally friendly applications.
