Polyvinyl alcohol PVA Performace
Polyvinyl alcohol (abbreviated as PVA) also can be called PVOH. It is a kind of heavy polymer, produced by polymerization and alcoholysis of vinyl acetate. PVA is white or light yellow floccus, granular or powdery in appearance. Its molecular formula is［CH2CHOH］n，and the molecular formula for some of the PVA is -［CH2CHOH］n-［CH2CHOOCCH3］m-. PVA is non-toxic, insipid and harmless. It is water-soluble and the solvent provide good viscosity and film building.
