Beschreibung
Zusammenfassung:	An autoignition propellant (AIP) is disclosed for use in conjunction with gas generative compositions for air bags to reduce the autoignition temperature of said propellant without adversely affecting the AIP's storage thermal stability. Said AIP consists essentially of A) a mixture of a) about 60 to 80% by weight KClO3, b) about 15 to about 30% by weight lactose and c) about 1 to about 10% by weight of an aliphatic polycarbonate and B) an autoignition lowering effective amount of superfine iron in an amount up to 10% by weight based upon the combined weight of A) and B). A method of using the AIP to lower autoignition temperatures and an air bag inflator containing the AIP are also disclosed.
