accelerate the depolycondensation of PU matrix [ 26 ]. The second step of mass loss forms a carbonaceous material between 290 and 380 °C. The T max for TPU-1 at second steps is 316.0 °C, while T max for TPU-2 is 308.7 °C. It is found that flame retardant

-linked carbonaceous materials. The obvious difference between the treated and untreated wood samples is that the mass losses and the final decomposition temperature (FDT) at this stage were increased of the treated samples simultaneously. These results mean that the
