Abstract

Process for obtaining inflammation-resistant foamed materials, bearing urethane groups, characterized in that polyesters, bearing hydroxyl groups, polyisocyanates, water and/or other propellants, catalysts and, where appropriate, subsequent agents, are reacted Auxiliaries, the polyesters being linear polyesters comprising two hydroxyl groups and a molecular weight of 1500 to 2000, preferably 200 to 800, and the polyisocyanates are solutions of polyisocyanates, bearing biuret groups, in monomeric polyisocyanates.
