Patent ID: 8287834

Claim:
A composition which is capable of generating nitrogenous gas by decomposition, comprising: from 20 to 80% by weight of azodicarbonamide, from 20 to 80% by weight of a nitrogenous reducing charge, from 0 to less than 10% by weight of at least one additive; said azodicarbonamide and said nitrogenous reducing charge representing at least 90% by weight of the composition, and the composition is devoid of oxidizing charge, and said nitrogenous reducing charge comprising at least one selected from the group consisting of: at least one compound from a first family of reducing components chosen from tetrazole, tetrazole derivatives and their salts, salts of bitetrazole and of its derivatives, 5,5â€²-azobitetrazole salts, polyvinyltetrazoles and their mixtures; and at least one compound from a second family of reducing components chosen from dicyandiamide, 1-hydrobenzotriazole, silicon nitride, nitroguanidine, guanidine nitrate and their mixtures.
