ABSTRACT:
There is provided a gas generating composition consisting essentially of a mixture of nitroguanidine, phase stabilized ammonium nitrate and an elastomeric binder. When the ammonium nitrate is phase stabilized with from about 7% to about 20%, by weight, of a potassium salt, the mixture is structurally and volumetrically stable over typical automotive operating temperatures and has a melting temperature in excess of 100.degree. C. The mixture generates large volumes of nitrogen and carbon dioxide when ignited with minimal generation of solids or toxic gases and is particularly useful as an inflating medium for automobile airbags.
