This paper gives the results of investigations on reducing the flammability of polyurethanes produced by Russian industry, based on polyether and polyester. An investigation was made of the effect of fireproofing agents on the physicomechanical characteristics of polyurethanes in the initial state (at 20°C) and after exposure to elevated temperatures (60, 80, and 100°C). The flammability of the developed composites was studied. A composite with the optimum combination of properties was determined.
