Abstract The thermal degradation of flexible polyurethane foam has been studied under different conditions by thermogravimetric analysis (TG); thermogravimetric analysis-infrared spectrometry (TG-IR) and thermogravimetric analysis-mass spectrometry (TG-MS). For the kinetic study; dynamic and dynamic+isothermal runs were performed at different heating rates (5; 10 and 20 °C min-1) in three different atmospheres (N2; N2:O2 4:1 and N2:O2 9:1). Two reaction models were obtained; one for the pyrolysis and another for the combustion degradation (N2:O2 4:1 and N2:O2 9:1); simultaneously correlating the experimental data from the dynamic and dynamic+isothermal runs at different heating rates. The pyrolytic model considered consisted of two consecutive reactions with activation energies of 142 and 217.5 kJ mol-1 and reaction orders of 0.805 and 1.246. Nevertheless; to simulate the experimental data from the combustion runs; three consecutive reactions were employed with activation energies of 237.9; 103.5 and 120.1 kJ mol-1; and reaction orders of 2.003; 0.778 and 1.025. From the characterization of the sample employing TG-IR and TG-MS; the results obtained showed that the FPUF; under an inert atmosphere; started the decomposition breaking the urethane bond to produce long chains of ethers which were degraded immediately in the next step. However; under an oxidative atmosphere; at the first step not only the urethane bonds were broken but also some ether polyols started their degradation which finished at the second step producing a char that was degraded at the last stage. © 2015 Elsevier B.V;
