Air bags have become important safety devices in many motor vehicles. Therefore, a rapid pressurizing system must be employed in airbags. Today’s different airbag inflationtechniques have been considered including stored gas system, solid-propellant gas generators, and hybrid systems. Amongthese, solid-propellant gas generator is the most common and reliable. In the solid propellant system, a solid grain is ignitedupon collision and generates gaseous combustion products toinflate the airbag. Over the past 30 years, different solid propellant gas generator technologies have been explored tomeet the stringent requirements for motor vehicle airbag applications [1]. Some ferrocene derivatives were used asaccelerator catalyst, but the major drawback of these compounds was migration in grain which decreases the safety properties of product
