Abstract (en)

The invention relates to a pyrotechnic composition generating nontoxic hot gases. The composition comprises essentially: - a binder which is the product of reaction of a hydroxylated glycidyl polyazide with a polyisocyanate, - an energetic plasticiser such as 1,2,4-butanetriol trinitrate, - an oxidising filler, at least 85 % of its weight consisting of ammonium nitrate. The composition, which does not contain any metal compounds, burns without producing solid residues with a rate of burning which is relatively independent of pressure. It is particularly well suited for gas generators for inflatable cushions operating without any filtration chamber.
