Water-soluble. Dissolving speed will accelerate with the rise of water temperature. The oil-resistant property is extremely high, and does not dissolve in almost all of the organic solvents, however, some of PVA can be dissolved in organic solvent, such as a kind of glycol, DMSO, and phenol.
Acid and alkali resistance:
Hardly effected by acid or alkali under a weak condition.
The melting point and the thermal decomposition starting point are close, and the decomposition gradually starts from higher that 180 C degrees.
Film formation property:
Apt to form yarn and film, and its physical performance, such as tensile strength, tear strength, abrasion resistance, is superior to other synthetic resins.
Moisture absorption property:
Compared with other water-soluble synthetic resins, moisture absorption property is lower and be less affected by the humidity.
