It is the object of this invention to provide an abrasion resistant gas generating composition. More particularly it is the object of this invention to provide an abrasion resistant gas generating composition in granular form for use as a gas generator in the inflation of passenger protective crash bags,<a href="http://www.lightcrusher.com/solutions/sand-mining-equipment.html">sand mining equipment</a>. A further object of the invention is to provide a granular abrasion resistant gas generating composition which is low in toxic products. A further object of the invention is to provide a method for manufacturing the granular abrasion resistant gas generating composition. Additional objects will appear from the specification and claims which follow. The objectives and advantages of the present invention are accomplished by the preparation of a granular composition comprising a metallic azide, oxidizers for the azide, and from about 1 percent to 10 percent by weight of the total composition of a cured solid polymeric binder composition having a high oxygen content and prepared entirely from solid binder ingredients having a melting point in the range of 45° C to 130° C,<a href="http://www.lightcrusher.com/solutions/granite-crushing-machine.html">granite crushing machine</a>. It has been found that such a composition when formulated as described hereinafter produces a gas generating composition which is resistant to abrasion under conditions of vibration and upon ignition releases gases which are predominately non-toxic. The improved abrasion resistance is substantially due to inclusion in the composition of the cured polymeric binder which serves a dual function. Thus, the binder composition acts as an internal adhesive holding the gas generating granules tightly together and also produces a solid coating around said granules which acts as a barrier imparting resistance to impact and abrasion.
