| Physical and chemical properties | Polyvinyl alcohol resin series are white solids with three types of appearance: flocculent, granular and powder; non-toxic, tasteless and pollution-free, and can be dissolved in water at 80--90℃. Its aqueous solution has good adhesive and film-forming properties; it is resistant to most organic solvents such as oils, lubricants and hydrocarbons; it has chemical properties such as esterification, etherification and acetalization of long-chain polyols. |
| Product Use | Used as warp sizing, emulsion stabilizer, rewetting binder, water-soluble film, etc. |
