“…It seems that H 2 O is also evolved in the range 410-500 • C (36-45 min), which is connected with the decomposition of the remaining Mg(OH) 2 . The last is also in agreement with the literature [18]. The evolution of HCl (m/z 36) above 450 • C (40 min) might be due to the oxidation of MgCl 2 [19].…”

“…The volatilized products formed during the thermal degradation process in TG test and the thermal degradation mechanisms were characterized by TG‐FTIR technique . The characteristic TG‐FTIR spectra of pyrolysis products of TPU‐0 and TPU/PMDA‐4 from 30°C to 700°C were shown in Figure A to B (with 3D photograph) and Figure A to D (with 2D photograph).…”

Summary In this paper, pyromellitic dianhydride (PMDA) was firstly used as fire safety agent for thermoplastic polyurethane (TPU). And, the fire safety improvement of PMDA in TPU was intensively investigated by limiting oxygen index (LOI), smoke density test (SDT), cone calorimeter test, and thermogravimetric/infrared spectroscopy, respectively. It has been found that PMDA could significantly improve the ignition level, and the LOI value increase to 28.5% when 8.0 wt% PMDA was incorporated into TPU; PMDA also could effectively suppress the smoke production and heat release during the combustion process. The peak heat release rate and total smoke release of the sample with 8.0 wt% PMDA were decreased by 68% and 22% compared with pure TPU in cone calorimeter test. The thermogravimetric/infrared spectroscopy results showed that PMDA could improve the thermal stability of TPU composites at high temperature and increased the release of CO2, H2O, and so on. All results confirmed that PMDA would have a good prospect in reducing the fire hazard of TPU.

In the present work, chitosan and magnesium hydroxide (MH) were successfully deposited on the surface of flexible polyurethane foam (FPUF). Due to the strong interaction, the coated foam with 10.3 wt% weightgain could be prepared by constructing one chitosan layer and one MH layer. Scanning electron microscopy images showed that this coating continuously covered the substrate. The combustion properties of FPUF were investigated by cone calorimeter and smoke density tests, and the gases released during the thermal degradation process were monitored by thermal gravimetric-Fourier transform infrared spectrometry. It was found that the FPUF with a chitosan/MH coating kept its shape and released less black smoke after being exposed to a butane flame for 10 s, while the pure foam was consumed completely. The cone calorimeter test data indicated that a reduction in the peak heat release rate of the foam with 10.3 wt% weight-gain achieved 52.6% relative to pure foam. Remarkably, the smoke density test results showed that the coating can significantly suppress the smoke production of FPUF. Moreover, the evolved gas products of FPUF during the thermal decomposition were effectively decreased after being covered with the hybrid coating.
