  • METHOD FOR PREPARING NOVEL NATURAL OIL BASED HIGH TEMPERATURE ISOCYANURATE CONTAINING POLYURETHANE THERMOSETTING RESINS
    Publication number: 20220267502
    Abstract: Soy-based high temperature products, or thermoset resins, are produced by solvent free polymerization of soy polyols and polyisocyanates at room temperature. The ratio of isocyanate equivalents to polyol equivalent used in the synthesis is greater than or equal to 3. The invented soy-based products are polyisocyanurate solid materials with excellent stability at high temperature. Heat resistance of the material is influenced by ratio of soy polyol and polyisocyanate.
