Product Description

 

Product Description

Polyvinyl alcohol (PVA) resin is a kind of heavy polymer. It is usually a white or slight yellow floccules, flake, granular or
powdery in appearance.
PVA is non-toxic, insipid and non-polluting. PVA is a kind of 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 chemical properties of polyols and can make esterification, etherification, acetalization reactions.

Application:
It has a wide range of uses, such as pastes, coatings, adhesives (such as transparent glue), stabilizers, dispersants,
emulsifiers, thickeners, sensitizers and fillers, and nasal glue (toys).
-Improves bonding strength
-Improves smoothness and surface gloss
-Improves oil resistance and abrasion resistance
-Improve film forming properties and chemical stability
