By means of a combined thermal analysis technique,, the thermal behaviour of rigid polyurethane foams containing additive antipyrenes was studied. The presence of phosphorus-and phosphorus/chlorine-containing antipyrenes based on phosphate and phosphonate and a combination of them led to decreases in the rates of heat and weight loss during heating. More steps of decomposition were formed and the interval of decomposition was widened and shifted to higher temperatures. Some thermal characteristics make it possible to predict the optimum antipyrene compositions and concentrations with minimum time, labour and material consumption under laboratory conditions. Rigid polyurethane foam (RPUF) is an organic material with a high tendency to burn. Its combustibility depends essentially on the thermal stability of the structural chemical bonds and the products of decomposition. As with other types of polyurethanes, its flammability is reduced by the addition of antipyrenes. The problem of selecting optimum antipyrene compositions for polymers is becoming an urgent necessity. It requires the development of laboratory methods which are minimum time-, labour-and material-consuming and can provide maximum insight into the inhibiting effect of antipyrenes, thereby allowing a comparative evaluation of their efficiency. A major shortcoming of the available flammability tests is their failure to meet these requirements. Directly proportional relationships between polymer flammability tests and thermal analysis data have, recently been found [1][2][3][4][5]. Systematic studies [6][7][8][9] in this field, however, are still scarce.The aim of this work was to study the effect of additive antipyrenes with different compositions and structures on the mechanism and kinetics of the total thermal decomposition reactions of RPUF, and the possibility of evaluating their effectiveness as combustion inhibitors.
