Abstract
Procedure for obtaining inflammation-resistant hard foamed materials containing urethane groups, characterized in that solutions of polyethers bearing hydroxyl groups, polyisocyanates carrying allophanate groups, water and other blowing agents, catalysts and, in case given, further adjuvants, said polylinear, preferably initiated with aromatics, having a molecular weight of 150-750 preferably 200-600 and said polyisocyanates containing nalophanate groups, those with at least 3 NCO groups and said blowing agent, represents at least 0.5 parts by weight, per 100 parts by weight of polyether, of water.
