Polyvinyl alcohol 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

Polyvinyl Alcohol (PVA) is a water soluble and biodegradable synthetic polymer. It is a dry solid, and is available

in granule and powdered forms. Grades include both fully hydrolyzed and partially hydrolyzed. PVA is an excellent adhesive with superior bonding strength, film forming and emulsifying properties. The film of PVA exhibits

outstanding resistance to oil, grease and solvents. In addition to its film forming property, it has excellent adhesion to both hydrophilic and hydrophobic materials. PVA has been extensively used in textile industry for warp

sizing and resin finishing; in paper industry for surface sizing and pigment coating; in the production of PVAc

emulsion as protective colloid; in the suspension polymerization of PVC as a dispersion agent; as binder for

ceramics, magnet, foundry cores and pigments.
