Most of polymeric materials, when exposed to high temperatures, heat flows or an open flame, are capable of exothermic oxidation reactions – combustion. That is why polymeric materials are fire hazardous. The studies on creating a non-flammable polymer materials are crucial, as such products can make our everyday life a lot more safe. Studies have been carried out to assess the effectiveness of the action of two types of fire retardants (graphene and an organic phosphorus-containing compound DOPO-THPO), introduced into an epoxy resin. Evaluation of the effectiveness of the fire-retardant action was carried out by the methods of oxygen index (OI) and flammability according to UL 94. For the investigated compositions, it was found that there is no direct correlation between the value of the oxygen index and the ability of the samples to maintain self-combustion. For these compositions, the total duration of residual combustion in vertical tests and the speed of flame propagation in horizontal tests are naturally correlated. It was found that if the total duration of combustion of five samples during vertical tests is 500 seconds or less, then these compositions during horizontal tests will fade, that is, formally, their flame propagation speed will be equal to zero.
