POLYVINYL ALCOHOL(PVA)

CAS:9002-89-5

Polyvinyl Alcohol (PVA) is an important synthetic polymer material

POLYVINYL ALCOHOL

Polyvinyl Alcohol (PVA) is a water-soluble synthetic polymer

Appearance: White flakes/powder
Solubility: soluble in hot water, slightly soluble in ethanol, insoluble in methanol, benzene, acetone, gasoline and other general organic solvents.
Thermal stability: when heated, it does not melt, and dehydrated decomposition occurs at about 150℃, and the color turns yellow.
Hygroscopicity: It has certain hygroscopicity.
Film forming: easy to form film, the formed film is colorless and transparent, with good mechanical strength.
Polyvinyl alcohol is a linear polymer with secondary hydroxyl group. The hydroxyl group in the molecule has high activity and can be esterified, etherified and acetalized. It also has the characteristics of resistance to weak acids, weak bases and organic solvents
