Abstract: Cool burning gas generant compositions for an automotive inflatable restraint system are provided that include a bismuth-containing compound selected from the group consisting of: bismuth citrate, bismuth subsalicylate, bismuth hydroxide, copper bismuth hydroxy nitrate, bismuth subcarbonate, bismuth suboxalate, and combinations thereof. The gas generant comprises at least one copper-containing component. The gas generant includes at least one oxidizer, fuel, and optional coolant. The maximum flame temperature at combustion (Tc) of less than or equal to about 1700K (1,427° C.). The cool burning gas generant composition generates liquid phase combustion products making it suitable for use in a filterless inflatable restraint system. Copper and bismuth present in the cool burning gas generant composition react to form an alloy having a melting point at or near the maximum flame temperature at combustion (Tc).

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.

Abstract: A gas generant composition for an automotive inflatable restraint system is provided with a fuel having a thermally stable crystalline hydrate compound with a water release temperature of greater than or equal to about 140° C. The thermally stable crystalline hydrate compound serves as a ballistic modifier, which can serve to increase burn rate, reduce pressure sensitivity, reduce temperature sensitivity, and the like. The thermally stable crystalline hydrate compound may be selected from the group consisting of: a copper phthalate hydrate, copper pyromellitate dihydrate, copper fumarate dihydrate, copper (3-nitrophthalate) dihydrate, and combinations thereof.
