PVA Product Characteristics and Instruction

1.Product Performance
Polymer is a kind of high polymer. It is white or light yellow floc, 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. 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, aceatalization etc.

2.Product Use
