Polyvinyl Alcohol(PVA)

Molecular formula:CH₂CHOH_n orCH₂CHOH_n-CH₂CHOOCCH_3m

characteristics

PVA resin is a kind of heavy polymer,it is non-toxic, insipid and harmless. PVA is water-soluble and the solvent provide good viscosity and film building. It can withstand oils, lubricants, hydrocarbons and most other organic solvents. PVA has better chemical stability and insulatibility, and provide ease in firm building; It possess the typical chemical properties of polyols and can carry out process of esterification, etherealization, acetalization etc.
