SIMION NACU PRACTICAL ASPECTS ON USING POLYTETRAFLUORETHYLENE (PTFE) IN PYROTECHNIC COMPOSITIONS
Polytetrafluorethylene PTFE is used in flare pyrotechnical compositions, together with a metallic fuel, usually magnesium or aluminum plus a binder. This paper presents new research on the flare pyrotechnical compositions for thermal decoys, obtained from polytetrafluorethylene (PTFE), carburants like aluminum or magnesium, phenol-formaldehyde resine and graphite. DTA differential thermal analysis is used to determine the thermal behaviour of energetic material and the auto-inflammation temperature. For performance characteristic of pyrotechnic compositions, the combustion velocity has been determined.
