The invention concerns pyrotechnic mixtures generating non-toxic gases characterised in that they essentially consist of a cross-linkable reducing binder based on epoxy resin or silicone resin, an oxidising filler based on ammonium perchlorate and a chlorine scavenger such as sodium nitrate and energetic additives consisting of a cupric compound such as cupric oxide or basic copper nitrate and of a nitrogenated organic compound such as, for example, nitroguanidin or guanidine nitrate. The filler can also contain potassium perchlorate. Said compositions b...


1. A pyrotechnic gas-generating composition comprising: a) a crosslinked reducing binder representing at most 10% of the total weight of the composition chosen from the group consisting of crosslinkable reducing binders based on silicone resin, based on epoxy resin and based on polyacrylic rubbers having reactive terminal groups; b) a main oxidizing filler representing between 50% and 75% of the total weight of the composition and comprising at least a mixture of ammonium perchlorate and a chlorine scavenger chosen from the group consisting of sodium...
