polyvinyl alcohol

White sheet, flocculent or powdery solid, odorless. Density: relative density of polyvinyl alcohol (25 °C / 4 °C) 1.27 ~ 1.31 (solid), 1.02 (10% solution. Glass transition temperature: 75 ~ 85 °C. Heat performance: heating in air more slowly to 100 °C, discoloration, brittleness. heated to 160 ~ 170 °C ether dehydration, loss of solubility, heated to 200 °C begin to decompose. more than 250 °C into a polymer containing conjugated double bonds. refractive index: 1 . 49 ~ 1.52. Thermal conductivity: 0.2w / (m · K). specific heat capacity: 1 ~ 5J / (kg · K). resistivity: (3.1 ~ 3. 8) × 10Ω · cm. ignition temperature (°C): 410 (powder) explosive limit% (V / V): 125 (g/m3) Solubility: soluble in water, in order to be heated to dissolve completely normal 65 ~ 75 °C. do not dissolve in gasoline, kerosene , vegetable oil, benzene, toluene, dichloroethane, carbon tetrachloride, acetone, ethyl acetate, methanol, ethylene glycol and so on. slightly soluble in DMSO. 120 ~ l50 °C soluble glycerol. but cold to room temperature to become jelly.
The main purpose
For the manufacture of polyvinyl acetal, resistance to gas pipelines and vinylon synthetic fibers, textile treatment agents, emulsifiers, paper coatings, adhesives and so on.
