Abstract

See full text

Gas generant compositions without highly toxic azides are provided which, upon combustion, are converted into gaseous products with only small amounts of solid combustion products thereby minimizing the gas filtration problem. A process for safely preparing gas generants which utilize the nitrogen containing fuel TAGN in the composition are provided. These compositions are especially suitable for inflating automotive and aircraft occupant restraint bags. The present invention advantageously and safely combines TAGN with phase stabilized ammonium nitrate (PSAN) to achieve production of a high volume of non-toxic gas with only small amounts of solid combustion products.
