General properties

Polyvinyl alcohol film：The density is 1.26-1.29g/cm3, the refractive index is 1.52, and it emits blue-white light after ultraviolet irradiation. Large water absorption, immersed in water can be dissolved, the moisture content of the fiber can reach 30%-50%, and the moisture content in the environment of 65%RH and 25 °C can also reach 4.5%. It can permeate water vapor, but difficult to permeate alcohol vapor, and it cannot penetrate organic solvent vapor, inert gas and hydrogen.
