  • Publication number: 20120305148
    Abstract: A malleable solid explosive that is in the form of a solid block consisting, for at least 98% of its weight, of a pulverulent explosive charge and of a liquid chosen from polyol polymers of the group of polyisobutylene polyols, polybutadiene polyols, polyether polyols, polyester polyols and polysiloxane polyols, whose number-average molecular mass is between 500 and 10 000, and mixtures thereof.

  • Patent number: 6916390
    Abstract: In the military field of explosive munitions, a semi-continuous process produces a composite explosive charge composing a charged solid polyurethane matrix, the charge of which is pulverulent and comprise at least one nitro-organic explosive, by introduction into a mould of a pastry explosive composition and then thermal crosslinking of this composition. The composition is obtained by mixing constituents essentially comprising a polyol prepolymer, a plasticizer, a polyisocyanate monomer and a pulverulent solid charge comprising at least one nitro-organic explosive. This simple and economic process makes it possible to dispense, without disadvantage, with the pot life/curing time of the composition compromise.

  • Patent number: 6080248
    Abstract: The invention relates to novel non-detonatable pyrotechnic materials which have a thickness of less than 500 .mu.m or a mass of less than 15 mg, whose combustion is self-sustainable after localized initiation by an electrical power of between 150 mW and 800 mW, for a time of between 20 ms and 600 ms, and which comprise from 25 to 80% by weight of an energy-releasing binder based on poly(glycidyl azide), or on poly(3,3-bis[azidomethyl]oxetane) or on a polyester or polyether and on 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.These novel materials are used as miniature gas generators, miniature propulsion units or miniature heat generators.
