A method of manufacture of pyrotechnics was developed using high-rate evaporation of magnesium onto a PTFE web [122,123].The magnesium was the fuel and the fluorine in the PTFE was the oxidizer. Given ignition, the PTFE would melt releasing the fluorine, and this would react with the magnesium releasing heat that would help sustain the process [124,125].
