In a dry, well-ventilated room, with room temperature around 5-30°C.
Keep away from heat sources, keep away from moisture, and avoid exposure to sunlight.
It is strictly prohibited to store together with volatile chemicals to prevent adsorption and deterioration.
Polyvinyl alcohol (PVA for short), organic compound, white flake, flocculent or powdered solid, non-toxic, tasteless, pollution-free, can be dissolved in 80--90 °C water. Slightly soluble in dimethyl sulfoxide. Its aqueous solution has good adhesion and film-forming properties; It has chemical properties such as esterification, etherification and acetalation of long-chain polyols. It is a water-soluble polymer with a wide range of uses, its performance is between plastic and rubber, and its uses can be divided into fiber and non-fiber two major uses.
