Non-detonatable pyrotechnic materials for microsystems

Non-detonatable pyrotechnic material, whose combustion is self-sustainable at atmospheric pressure or at a pressure close to it, comprising an energy-releasing binder and ammonium perchlorate, characterized in that it has a thickness of less than 500 .mu.m or a mass of less than 15 mg, in that its combustion is self-sustainable after localized initiation by an electrical power P such that 150 mW.ltoreq.P.ltoreq.800 mW for a time t, such that 20 ms.ltoreq.t.ltoreq.600 ms, and in that it comprises:

• from 25% to 80% by weight of an energy-releasing binder based on poly(glycidyl azide) (PGA), or on poly(3,3-bis[azidomethyl]oxetane) (BAMO), or on a polyester and at least one energy-releasing plasticizer, or on a polyether and at least one energy-releasing plasticizer;
• from 10% to 70% by weight of ammonium perchlorate, the particle size of which is between 0.5 and 30 .mu.m;
• and
• from 0% to 45% by weight of at least one nitramine.
