Polyvinyl Alcohol | PVA | 9002-89-5
Typical Property:
Polyvinyl Alcohol (PVA) resin is a high molecular polymer with a chemical formula of (CH2CHOH)n. It is a commonly used adhesive with good film forming properties, bonding properties and thermal stability. Its water solubility is related to the degree of alcoholysis. When the degree of alcoholysis is below 88%, polyvinyl alcohol can be dissolved in normal temperature water; when the degree of alcoholysis reaches 97%, hot water of 60~80 degrees C. should be required for dissolution.
