20.500.12556/DiRROS-15827 Flame retardant behaviour and physical-mechanical properties of polymer synergistic systems in rigid polyurethane foams In the presented work, the influence of two flame retardants—ammonium polyphosphates and 2,4,6-triamino-1,3,5-triazine on the polyurethane foam (PUR) systems were studied. In this paper, these interactive properties are studied by using the thermal analytical techniques, TGA and DTA, which enable the various thermal transitions and associated volatilization to be studied and enable the connection of the results with thermal and mechanical analysis, as are thermal conductivities, compression and bending behavior, hardness, flammability, and surface morphology. In this way, a greater understanding of what the addition of fire retardants to polyurethane foams means for system flammability itself and, on the other hand, how this addition affects the mechanical properties of PUR may be investigated. It was obtained that retardants significantly increase the fire resistance of the PURs systems while they do not affect the thermal conductivity and only slightly decrease the mechanical properties of the systems. Therefore, the presented systems seem to be applicable as thermal insulation where low heat conductivity coupled with high flame resistance is required. flammability polyurethane polymer foams thermal conductivity mechanical properties open access vnetljivost poliuretanski polimer pene toplotna prevodnost mehanske lastnosti odprti dostop true false true Molecular Diversity Preservation International Angleški jezik Slovenski jezik © 2022 by the authors.
