Polyvinyl Alcohol

Polyvinyl alcohol (PVOH, PVA, or PVAl) is a water-soluble synthetic polymer. Polyvinyl alcohol is the raw material to make polymers. Polyvinyl alcohol is used as an emulsion polymerization aid, as protective colloid, to make polyvinyl acetate dispersions.

Polyvinyl Alcohol (PVA) is a synthetic, biocompatible and toxicologically safe polymer. Polyvinyl alcohol is used for mounting cells on slides for detection of cell-surface antigens by immunofluorescence. It is useful as an anti-fading agent. It has various pharmaceuticle applications. In tablet…
