Abstract

Procedure for obtaining non-flammable urethane-bearing foamed materials from polyethers bearing hydroxyl groups, polyisocyanates, water and/or other propellants, catalysts and, if appropriate, other adjuvants, characterized in that as polyethers they are made React those that carry at least two hydroxyl groups and have a molecular weight of 3500 to 10,000, preferably 4,000 - 8,000, in which at least 10% of the existing hydroxyl groups are primary hydroxyl groups, and as polyisocyanates are react polyisocyanate solutions, bearing biuret groups, on monomeric polyisocyanates.
