The different grades of PVA exhibit varying levels of solubility. Fully hydrolyzed PVA, for instance, is more soluble in water compared to partially hydrolyzed PVA. This difference is crucial when selecting the appropriate grade for a specific application. Industries often utilize lower degrees of hydrolysis for applications requiring a less viscous solution, while higher degrees are preferred when a stronger film-forming property is required.
