Epoxy foams with their high technologic parameters and performance characteristics have a special place in a field of poly-mer insulation materials based on reactive oligomers. However, polyepoxy foams are highly flammable, which significantly lim-its their use in the construction industry. The purpose of the work is to develop effective methods for reducing the flammability of cast epoxy foams and increasing physical and mechanical properties. Research objectives: to establish the influence of the chem-ical nature and content of additive and reactive bromine- and phosphorus-containing compounds on the heat resistance, flam-mability and performance properties of cast epoxy foams and to develop low-flammability polyepoxy foams with high physical and mechanical characteristics. The thermal properties of epoxy foams were studied using a DuPont-9900 multimodular thermal analytical complex. Experimental data on the influence of the apparent density of polyepoxy foams and the oxygen concentration in the oxidizer flow on the speed of flame propagation along the horizontal surface of polyepoxy foams are presented. It was re-vealed that the chemical nature of amine hardeners has virtually no effect on the heat resistance and flammability of polyepoxy foams. It has been established that phosphate plasticizers are ineffective flame retardants for polyepoxy foams, and the chemical structure of additive organobromine flame retardants has little effect on their effectiveness. It has been shown that microencap-sulated flame retardants are inferior in flame extinguishing efficiency to additive flame retardants. It was revealed that effective flame retardants for casting polyepoxy foams are phosphorus-containing oligoester methacrylate and epoxidized waste from the production of tetrabromdiphenylol propane.
