| Abstract: | A comparison of alumina (Al2O3) and boehmite (AlOOH) in (ammonium polyphosphate/melamine polyphosphate/metal oxide) ternary system was performed in poly(methyl methacrylate) on thermal and fire‐resistance properties. A Design of Experiments (DoE) was then done for highlighting the best formulation out of both ternary systems. Laser flash analysis and scanning electron microscopy helped to explain some of the observations made by DoE. Mechanisms in both ternary systems during degradation also were investigated and modes of action could be presented based on pyrolysis‐combustion flow calorimetry, Raman spectroscopy and X‐ray diffraction.
