Abstract

Des compositions d'agent générant du gaz thermostables comprennent une combinaison de nitroguanidine, d'un ou plusieurs combustibles non-azide à teneur élevée en azote, et d'un nitrate d'ammonium stabilisé en phase ou d'un agent d'oxydation non métallique similaire qui, lors d'une combustion, produit un rendement supérieur de produits gazeux par unité massique d'agent générateur de gaz, un faible rendement de produits de combustion solides et des propriétés acceptables de vitesse de combustion, de stabilité thermique et balistique. Ces compositions sont particulièrement appropriées au gonflage de coussins gonflables de sécurité dans des dispositifs de retenue de passagers.
