Abstract: A gas generant formulation for a side impact airbag that includes a primary fuel, a primary oxidizer, a secondary fuel, and a secondary oxidizer. The secondary fuel includes at least melamine nitrate in an amount that is in a range of about 1.00% by weight to about 10.00% by weight. The secondary oxidizer includes at least potassium perchlorate that is in an amount that is in a range of about 1.00% by weight to about 10.00% by weight. The formulation provides a burn rate that is at least 50 mm/sec at 40 MPa and a burn rate slope that is equal to or less than 0.40.

Abstract: Cool burning hydrate fuels are provided for gas generant compositions for automotive inflatable restraint systems. The cool burning hydrate fuel is a compound comprising carbon, hydrogen, oxygen, a transition metal, and optionally nitrogen. The cool burning hydrate fuel is a transition metal salt of an organic compound or transition metal complex salt having (i) at least one functional group selected from the group consisting of: amide, imide, hydroxyl, carboxylic acid, and combinations thereof, (ii) an oxygen-to-carbon mole ratio of greater than or equal to about 0.5, (iii) at least one-half a water molecule of hydration, and (iv) an exothermic heat of formation of at least about ?400 KJ/mole. The fuel may have a water release temperature of ?about 140° C. The cool burning hydrate fuel may be one or more of copper cyanurate dihydrate, a copper melamine oxalate dihydrate, and a copper malonate hydrate.
