Abstract: The present invention provides pyrotechnic gas generator compounds and a method of obtaining them. Said compounds have a composition which comprises: an oxidizing charge which comprises at least one inorganic perchlorate and which does not comprise a chlorine scavenger; and a crosslinked, oxygen-containing hydrocarbon binder obtained by crosslinking an elastomer in the presence of at least one crosslinking agent and at least one oxygen-containing plasticizer for said elastomer; said elastomer having a molecular weight of more than 200 000 and being preferably selected from polyesters and polyacrylates; said at least one oxygen-containing plasticizer being composed of a plasticizer of which the molecular weight is greater than 350 g/mol and the oxygen balance equal to or greater than ?230 %, of a mixture of such plasticizers with one another or of a mixture of at least one such plasticizer with at least one other oxygen-containing plasticizer. Said compounds can be obtained continuously by extrusion.

Abstract: The present invention provides a pyrotechnic gas generating composition and pyrotechnic compounds able to be obtained from said composition. Said composition comprises basic copper nitrate, guanidine nitrate, a specific additional reducing charge, and/or a specific additional oxidizing charge as well as a specific binder.

Abstract: The present invention relates to a gas-generating pyrotechnic composition, this composition being characterized in that it comprises a first oxidizing charge consisting of ammonium perchlorate and a second oxidizing charge consisting of a metal oxide chosen from the group consisting of copper oxide, manganese oxide and a mixture of these two compounds, the weight ratio between the first oxidizing charge and the second oxidizing charge being less than 1, the said composition also including a reducing charge in the form of a nitrogen-containing organic compound chosen from the group consisting of nitroguanidine, guanidinium nitrate, oxamide, dicyandiamide and metal cyanamides.
