“…This should be investigated in the future and if such trend exists, then the changes in the yield and composition of decomposition products with heating rate will hopefully justify the region of consistency found and explain the changes noted in the heat of reaction. This hypothesis is also supported by the findings from Rath et al [8] where a linear relationship is found between the final char yield of woods and their heat of reaction. While char yield is not a suitable variable for the case of foam due to its low value, the yields of various gaseous products are of interest.…”

“…The study of Rath et al [8] involved the decomposition of wood in nitrogen and two wood species, spruce and beech were investigated. The authors also studied the effect of using non-hermetic lid, different sample mass and different purge flow rates have on the heat of reaction.…”

“…Rath et al [8] show in their study on woods that the curvature is caused by the additional radiation heat flow between the sample and the furnace which is developed from the difference in emissivity between the sample and reference. Their study demonstrates that when lid is used, the emissivity between the sample and reference remains identical and the curvature is reduced.…”

The heat of reaction for the decomposition of polyurethane foam and its melt are determined from the heat flow measurements obtained through simultaneous differential scanning calorimetry and thermogravimetric analysis. Under nitrogen environment, the decomposition of foam experiences two endothermic pyrolysis reactions based on the experimental results. Through the investigation on the sensitivity of heat of reaction to heating rate and sample mass, a region where the heat of reaction remains constant is found for the melt samples tested. This consistent region includes heating rate from 5 to 20 °C/min and sample mass between ~20 and ~50 mg. No consistent region is found for the foam samples because of the reduced accuracy in the heat flow measured. For the foams and melts tested, the consistent heat of reaction for the second reaction ranges from endothermic 164 -295 J/g while the recommended heat of reaction for the first reaction ranges from endothermic 610 -1023 J/g.

“…For example, the thermal stability of polymethylmethacrylate (PMMA) is relatively insensitive to oxygen [1] when compared with polypropylene (PP) and polyethylene (PE) which both show a marked decrease in thermal stability as oxygen concentration is increased [2]. During wood pyrolysis in an inert environment, the volatile formation process is endothermic [3], but in oxidative environments such as air, oxidative reactions occurring near the surface are exothermic and can lead to visible glowing.…”
