Flame resistant polyurethane materials containing melamine-derived additives

摘要: Polyurethane foam is disclosed having improved flame retardancy, charring, and intumescent properties. The prepared from a reaction mixture comprising at least one isocyanate or diisocyanate, blowing agent, surfactant, catalyst, reactive hydroxyl-terminated oligomeric liquid melamine derivative. resulting provides substantial resistance to burning. A melamine-derived compound alkyl alkoxy groups, with hydroxy (-OH) termination(s) have proved be particularly useful in connection polyurethane foam.
