The invention relates to new non-detonable pyrotechnic materials which have a thickness of less than 500 μm or a mass of less than 15 mg, which are self-combustible after specific initiation by an electrical power of between 150 mW and 800 mW, for a time. between 20 ms and 600 ms and which comprise from 25 to 80% by weight of an energetic binder based on poly (glycidyl azide), or poly-3,3-bis (azidomethyl) oxetane, or polyester or polyether and d '' at least one energy plasticizer, from 10 to 70% by weight of ammonium perchlorate whose grain size is between 0.5 and 30 μm, and from 0% to 45% by weight of at least one nitramine.n n n These new materials are useful asngas microgenerators, micropropellers or microgeneratorsnheat. |
