  • Manufacture of pyrotechnic objects by a dry process; pyrotechnic objects
    Patent number: 8216402
    Abstract: The present invention relates to a dry process for the manufacture of pyrotechnic objects from at least one reducing charge selected from guanidine derivatives, metal hydrides, alkali metal hydrides and alkaline earth metal hydrides, and at least one oxidizing charge selected from alkali metal nitrates, alkaline earth metal nitrates and basic metal nitrates, at least one of said reducing and oxidizing charges having the property of flowing under stress. Said process makes it possible to obtain pellets and small tablets directly by compaction/compression, to obtain granules, usable as such, by compaction and then granulation, and to obtain compressed objects by compaction, granulation and then compression. The high-performance pyrotechnic objects obtained constitute a further subject of the invention.

  • Gas-generating pyrotechnic compositions with a binder and continuous manufacturing process
    Patent number: 6824626
    Abstract: The invention is directed to a solvent-free gas-generating pyrotechnic composition, and a method for continuously manufacturing the composition in a twin-screw mixer-extruder, the composition including a binder, a nitrogenous organic compound, an oxidizing filler, and optionally at least one additive; the oxidizing filler including an ammonium perchlorate and a chlorine scavenger; the binder including at least one polymer, having a molecular mass greater than 200,000 and selected from a polyester polymer and an acrylic ester, and wherein the binder uncliding at least one liquid constituent selected from a polyester resin and a plasticizer.
