Polyvinyl Alcohol PVA PVOH Wanwei Flakes 20-99 100-35 120

Polyvinyl alcohol is an excellent water-based adhesive. The general product is flake, granular or flocculent. It is not easily soluble in cold water. Heating is generally required during dissolution. After being finely pulverized and surface treated, it has better cold water dissolving performance. But because of its thermoplasticity, pulverization becomes particularly difficult. Our factory adopts a special liquid nitrogen low temperature cooling process to ensure that the powder of the crushed material is uniform. So that the material has excellent water solubility.
