Thermokinetic degradation studies of an airbag gas generant ternary mixture comprising NaN3, KNO3, and SrNO3 are carried out for the first time using simultaneous differential scanning calorimetry–thermogravimetric analysis. The results point toward the fact that the use of dual oxidizers has improved the reactivity of the azide‐based airbag gas generant mixture and reduced the amount of residual masses remaining after degradation to a minimal value of 2%. The activation energy of the mixture is also found to be increased to a maximum value of 249 kJ mol−1 which is better than the conventional airbag mixtures. The ballistic property studies done on the ternary mixture show that it can activate the airbag within 43.3 ms of crash which is very much an improved timeframe compared to the existing airbag mixtures. The study indicates that stoichiometric mixture containing NaN3/Sr(NO3)2/KNO3:75/12/13 by weight can be used as a potential airbag gas generant for automotive airbags. The blended mode methodology used in this research work combining the thermokinetic and ballistic property measurement can be effectively used to evaluate the performance parameters of airbag gas generants.
