Polyvinly Alcohol PVA
Click here to get more.
Polyvinyl alcohol (PVA) resin is a high polymer. It is usually a white or slightly yellow flocculant with a flake, granular or powdery appearance. PVA is non-toxic, odorless, and non-polluting. PVA is a water-soluble resin with good chemical stability. It also has good adhesion, film-forming ability, insulation, oil resistance, abrasion resistance and gas barrier properties, and has typical polyol chemical properties, which can enable esterification, etherification, and acetylation reactions.
