Abstract

At high temperatures, mineral fiber insulation is affected by the thermal degradation of its binder. Since in all cases the binder decomposes exothermically, there is a need to predict the maximum temperature attained in the layer so that the maximum use temperature of the fiber insulation is not reached. This paper advances a method of solution. Firstly, the binder decomposition kinetics is determined using thermal analysis. These results are then fed into a numerical model; thus the evolution of the temperature and binder concentration profiles is obtained. The results are then discussed and compared with experimental data on a hot plate.
