As a bond in wood, paper, cloth and in porous material.
In the paper industry, polyvinyl alcohol is used in the making of adhesives and paper boards. This chemical compound may also be used to thicken or modify polymer glues or glues made with polyvinyl acetate. PVAs may also be used as paper coating to increase its tensile strength and prevent easy tear or breakage. Much of PVA is used in the textile and paper industries. These synthetic polymers provide strength to sheets of textiles and helps paper products resist stains from greases and/or oily products. Polyvinyl acetate is a component of a widely-used type of glue, referred to variously as wood glue, white glue, carpenter's glue, school glue or PVA glue. Polyvinyl acetate was discovered in Germany in 1912 by Dr. Fritz Klatte.[2]. Confidence votes 144. PVA glue can be used as a bond in wood, paper, cloth and in porous material. It is the most commonly used wood glue. It is also termed as carpenter's glue or yellow glue. Sometimes white glues are also used in proving bond between wooden surfaces. PVA or polyvinyl alcohol is a synthetic form of polymer that has no color, no odor, and can be dissolved in water. Polyvinyl acetate, PVA, PVAc, poly(ethenyl ethanoate), is a rubbery synthetic polymer with the formula (C4H6O2)n. It belongs to the polyvinyl esters family with the general formula -[RCOOCHCH2]-. It is a type of thermoplastic.[1]. It is a type of thermoplastic. Polyvinyl acetate is a component of a widely used glue type, commonly referred to as wood glue, white glue, carpenter’s glue, school glue, Elmer’s glue (in the US), or PVA glue.”.
