PVA (Strom 1799,2099,2488,1788,0588) Sonnenschein Lee

Introduction 1. Name: Poly vinyl Alcohol(POVAL), PVA 2. Molecular formula: [C2H4O]n 3. Molecular weight: 44.05 4. Physical Property: Density: relative density of polyvinyl alcohol (25 °C / 4 °C) 1.27 1.31 (solid), 1.02 (10% solution. Heating performance: it will be discolored slowly heated to above 100 °Cin the air, embrittlement. Heated to 160 170 °C etherification dehydration, loss of solubility, heated to 200 °C begin to decompose. More than 250 °C into the polymer containing conjugated double bonds. 5. Chemical properties: Soluble in water, heated to completely dissolve the general need to 65 75 °C. Not dissolve in gasoline, kerosene, vegetable oil, benzene, toluene, dichloroethane, carbon tetrachloride, acetone, ethyl acetate, methanol, ethylene glycol, etc., slightly soluble in DMSO. 120 l50 °C soluble glycerol, however, a jelly when cold to room temperature. 6. Specification: power 1799, 2099, 2488, 1788, 0588 7. Appearance: White powder Detail 1. Transport or Storage: Stored in a ventilated, cool and dry place, away from fire. Transport should be handled with care to prevent damage to packaging. 2. Usage: Fiber can be divided into basic and non-fiber products that we tend to non-fiber, more extensive use, can be used in coatings, adhesives (to prevent the paint from the skin, loss), textile, construction, wood processing, paper making, printing . Play a major role in bonding. 3. Features: And CMC, have a customer needs the product price, must first ask him what is specific to the viscosity and specific purposes.
