WANWEI PVA 1799

Wanwei PVA-1799 is a high-viscosity 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 25-35 mPa·s (4% aqueous solution, 20°C), it is widely used in high-strength adhesives, textile sizing, paper coatings, and construction paints. PVA-1799 is easily soluble in hot water, forming films with high transparency and mechanical strength. It is also biodegradable and non-toxic, making it suitable for food packaging, pharmaceuticals, and personal care products.
