Fire Retardancy of Polyureas
Journal of Fire Sciences
In this study, a variety of additives have been evaluated as potential fire retardants for polyureas with cone calorimetry being the method of evaluation. The additives that have been evaluated include minerals (alumina trihydrate), bromine-, nitrogen-, and phosphorus-based fire retardants. The major criteria for evaluation are the reductions in the peak heat release rate and the total heat released, the evolution of smoke and dripping.
