Polyvinyl Alcohol PVA 2488 1788 120mesh

the physical and chemical properties of Polyvinyl Alcohol are introduced. 

Polyvinyl alcohol, alias PVA, is a water-soluble organic compound, generally white or cream-colored solid, its chemical structural formula is [C2H4O]n, and the relative molecular weight is 44.053. Soluble in water, slightly soluble in dimethyl sulfoxide, insoluble in gasoline, kerosene, petroleum ether, vegetable oil, benzene, toluene, dichloroethane, ethylene glycol, carbon tetrachloride, acetone, ethyl acetate, methanol, etc. various organic solvents.

Construction adhesives and adhesives Construction adhesives made from polyvinyl alcohol include putty adhesives, paint adhesive base materials, etc., and their scale accounts for more than 40% of the total. At present, the most widely used are PVA17-99, PVA20-99, two medium-viscosity adhesives, and PVA24-99, PVA26-99, two high-viscosity adhesives. In addition to construction adhesives, polyvinyl alcohol can also be used to make adhesives for paper, wood, textiles, office glues and high-grade paint bases, mainly used in paper, wood, textiles, office glues and high-grade paint bases The technical content of these glues is relatively high and requires a high level of compounding.
