Polyvinyl Alcohol (PVA)
Polyvinyl Alcohol (PVA), a white / yellowish granule or powder is a stable, non-toxic and water-soluble polymer. It has good film forming properties, the film formed from it has excellent adhesion, solvent resistance, abrasion resistance, high tensile strength and great oxygen barrier properties. Because it has hydrophilic and hydrophobic functional groups, it can act as a surfactant and can be used as a protective colloid in polymer emulsification and suspension polymerization.
