A method for making a propellant composition that results in a desirable gas output when combusted. The propellant can be part of an inflator used in a vehicle for inflating an air bag. The propellant has a relatively low burn rate exponent of no greater than about 0.7. The propellant is substantially dense, with the propellant having a density that is at least 85% of theoretical density. In making the propellant, its density can be reduced using a roller mill that flattens the propellant to a controlled thickness. The propellant preferably includes phase-stabilized ammonium nitrate and fibrous cellulose. |
