Polyvinyl Alcohol is a synthetic polymer represented by the formula (C2H4O)ₙ. It appears as a white to slightly yellow granular or powdery solid. PVA’s molecular weight varies, typically ranging from 24,000 to 120,000, depending on its grade. The polymer is characterized by its high solubility in water and ability to form films. Polyvinyl Alcohol 24-88, a common grade, exhibits a typical purity of ≥93.5%. This grade also demonstrates viscosity from 45-60 mPa·s, making it suitable for diverse industrial applications where viscosity and film-forming are critical. Handling of PVA should align with standard industrial protocols.
