Poly(vinyl alcohol) (PVOH, PVA, or PVAl) is a water-soluble synthetic polymer. The chemical formula for Poly(vinyl alcohol) (PVOH, PVA, or PVAl) is CH2CH(OH). PVA has complete or partial hydrolysis of polyvinyl acetate to remove the acetate group. PVA It is resistant to grease, solvents, and oils and has high aroma and oxygen barrier properties. It is also flexible with high tensile strength.
Used in papermaking, textile curing, as thickener and emulsion stabilizer in PVAc adhesive formulations and various coatings.
