Appearance: white or cream solid
Steam pressure: 811.9 ± 0.0 mmHg at 25 ° C
Refractive index: 1.381
Storage conditions: sealed at normal temperature, away from light, ventilated and dry place 2 Store in a cool and ventilated warehouse. Keep away from fire and heat source. It shall be stored separately from oxidant and shall not be mixed. 3. equip with corresponding types and quantities of fire-fighting equipment. The storage area shall be equipped with appropriate materials to contain the leakage.
Stability:
1. stable under normal temperature and pressure
Avoid heat, open fire, high temperature and moisture absorption. It will not melt when heated. It will decompose at about 150 ℃ and turn yellow.
2. it can resist the corrosion of ACID, alkali, grease and lubricant.
Solubility in hot water

General description:
Polyvinyl alcohol (PVA) is a vinyl water-soluble polymer, which can be used as non-ionic surfactant. It can also be used as a biodegradable polymer in adhesives, coatings, textiles, ceramics and cosmetics. It has good transparency, chemical resistance, toughness and antistatic properties.
Application:
PVA can be used to prepare microspheres and further used as biodegradable microcarriers.
