Molecular Formula: (C2H4O)n
Molecular Weight: 44.0526
Synonyms: Vinyl alcohol – polymerised;Polyvinyl alcohol;PVA
Polyvinyl alcohol is a resin with Avirulent insipidity, no pollution, can dissolve in the 80-90C water.
-Solution has good adhesion and film.PVA can be seen as a linear polymer with a hydroxyl polymer.
-Hydroxyl of molecules which has high activity can be a typical chemical reaction of low-alcohol, such as esterification, etherification, acetal, etc and can also react with a number of inorganic compounds or organic compounds.
Solubility
The Polyvinyl alcohol powder can be dissolved in water. PVA with Less than 95%alcoholysis degree can
be dissolved in water at room temperature and PVA with more than 99.5% alcoholysis degree can only be
dissolved in hot water above 95C.
Thermal Stability
The heat can make PVA soften and there is no significant change below 40C but 160C or more, for a long time
heated ,it will gradually be colored .when 220C above it is decomposed to produce water, acetic acid, acetaldehyde
and propylene aldehyde.
Chemical Resistance
PVA is almost free from weak acid, weak base, or the impact of organic solvents, oil is very high.
