Mass spectrometry and chromatography are used to study the decomposition products of Teflon mixtures of the “Fluralite-4” brand with magnesium, tungsten, and titanium, activated by mechanochemistry. The temperature and energy parameters of water and carbon dioxide release are determined, volatile products of Teflon depolymerization are detected and identified, i.e., tetrafluoroethylene, trifluoromethylene, trifluoroethylene. It is shown that the introduction of metal mixtures in the composition significantly affects the decomposition processes of Teflon.
