WANWEI PVA 2099

Wanwei PVA-2099 is a low-viscosity, fully alcoholized polyvinyl alcohol (PVA) known for its excellent film-forming, adhesive, and chemical stability properties. With a degree of alcoholysis exceeding 99% and a viscosity typically ranging from 20-30 mPa·s (4% aqueous solution, 20°C), it is widely used in adhesives, textile sizing, and specialized industrial applications. PVA-2099 is easily soluble in hot water, forming films with high transparency and mechanical strength. Its biodegradable and non-toxic nature makes it suitable for environmentally friendly applications.
