An ammonium nitrate and paraffinic material based gas generating composition is provided. The gas generating composition includes ammonium nitrate as a oxidizer, mixed with a paraffinic material as a fuel. Examples of paraffinic material include paraffin wax, and broadly includes polyolefins. Polyolefins include polyethylene, polypropylene and polybutylene. Additionally, as alternatives, the gas generating composition of the present invention can also include a small quantity of magnesium stearate, potassium perchlorate or alternatively, RDX. The ammonium nitrate oxidizer, the paraffinic material fuel and the additional alternative components are combined and mixed in a predetermined stoichiometric ratio. The gas generating composition is devoid of metal oxides and produces virtually no particulate and slag upon ignition. It also produces an acceptable, low level of undesirable trace effluents such as carbon monoxide, and nitric oxide, both of which are inherently present in nonazide gas generating compositions. The gas generating composition is environmentally friendly after the deployment of the gas generant and abrasive damage to the tooling used in the manufacture of the gas generating composition is minimized.
