Physical properties
Appearance: white free-flowing powder, odorless and tasteless.
Solubility: Polyvinyl alcohol powder (PVA) 17-88 and 24-88 type are partially alcoholy-soluble types which can be soluble in room temperature water. It is prohibited to use when the temperature drops to below 0 degree C; when the temperature is below 10 degrees C, sufficient dissolution time is required for dissolution, usually takes 5-10 minutes.
Solution stability: Aqueous solution of low viscosity Polyvinyl alcohol is stable at room temperature and does not deteriorate during storage.
Film Formability: Due to the high adhesion strength between Polyvinyl alcohol molecules, Polyvinyl alcohol is easy to form a film, which has colorless and transparent smooth surface with high mechanical strength and good solvent resistance.
