Abstract
Urethane and oxazolidone-containing isocyanurate foams characterized by cracking resistance and scorching resistance and thermal stability at a temperature of about 160.degree. C. or higher. These foams are produced by reacting at least one polyisocyanate with at least one polyepoxide and at least one polyol in the presence of catalyst, surfactant, and blowing agent.
