  • Low temperature autoignition material
    Patent number: 6645326
    Abstract: The autoignition compositions of the present invention ignites in the temperature range of 120° C. to 160° C. The autoignition compositions are thermally stable at 107° C. for 400 hours and are thermally stable during thermal cycling. The preferred composition for the autoignition composition comprises equal weight percentages of the following chemicals: nitroguanidine, Sb2S3, and AgNO3. An ignition temperature adjuster selected from the group consisting of teflon powder, graphite powder, ammonium perchlorate, MoS2, and FeS can be added to the preferred autoignition composition.
    Type: Grant

  • Gas generant compositions containing guanidines
    Patent number: 5985060
    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.
