초록

Gas generant compositions and methods of processing are provided which produce or result in a relatively high burning rate and low burning rate pressure exponent, while also desirably providing a high gas output, as compared to normal or typical gas generant formulations such as used in association with vehicle occupant restraint airbag cushions.

1. A gas generant composition comprising:between about 30 and about 60 wt % of a non-azide gas generating fuel, between about 15 and about 55 wt % metal ammine nitrate oxidizer, between about 2 and about 10 wt % metal oxide burn rate enhancing and slag formation additive, and between about 0 and about 35 wt % ammonium nitrate supplemental oxidizer, wherein the metal ammine nitrate oxidizer is present in a greater relative amount than the ammonium nitrate supplemental oxidizer and wherein the gas generant composition provides a burn rate in excess of 0.45...
