Abstract
A gas generant propellant composition having low flame temperatures comprng (a) an elastomeric binder consisting of a mixture of polyethylene capped polypropylene glycol and a dihydroxy tetrazole selected from the group having the formulas: ##STR1## (b) a curative agent such as the biuret trimer of hexamethylene diisocyanate; (c) a plasticizer agent such as 1-methyl-5 (methoxyethyl) tetrazole; (d) a coolant agent such as oxamide; and (e) a deflagrating agent selected from the group consisting of: dihydrazinium 3,6-bis(5-tetrazolyl)-1,2-dihydrotetrazine, dinitrosopentamethylenetetramine, the reaction product of glyoxal and hydrazine and the ammonium salt of 5-nitramino tetrazole.
