Abstract
The present invention relates to improved non-azide gas generants and methods for their manufacture for use in an automobile gas bag system. This discovery overcomes the problems of moisture and thermal cycling in a non-azide gas generant pellet through the use of at least two fuels selected from guanidine nitrate, nitroguanidine, triaminoguanidine nitrate, diaminoguanidine nitrate and monoguanidine nitrate and an oxidizer system comprising mixtures of strontium nitrate, sodium nitrate and ammonium perchlorate.
