Polyvinyl alcohol (PVA, PVOH) are water-soluble resins of low toxicity.Resins at high % hydrolysis require heating at~96°C in water for solution.Resins of lower % hydrolysis can be dissolved at progressively lower temperatures with 88% hydrolyzed resin requiring only 85°C for solution.
Soluble in: hot glycerol, hot glycols, hot water.
