초록 ▼

Automotive airbag gas generant formulation providing alternative to commercially used formulations containing sodium azide. The composition comprises from about 25% to about 75% by weight of a heterocyclic compound having the following structure: [Figure] wherein R is selected from hydrogen, －CO2X, and －OX and X is a cation providing an anhydrous salt. The other principal ingredient of the composition is from about 25% to 75% by weight of an anhydrous oxidizing salt having a cation selected from metals of Group I-A of the Periodic Table (except sodium), calcium, strontium, or barium, and an anion which is essentially free of carbon, hydrogen, or halogens. From about 0% to 2% of a binder can be added, if necessary. An automotive airbag inflator containing the composition and a method for generating gas comprising the step of igniting the composition stated above are also disclosed.
