Abstract
A pyrotechnic gas generating composition comprising a fuel and an oxidizer, the composition upon combustion generating a gas and a non-gaseous composition comprising a metallic salt or oxide, the metallic salt or oxide being a highly flowable liquid at the flame temperature of the composition upon combustion, and a viscosity modifier which is present in an amount to render the liquid substantially non-flowable at the flame temperature. Also disclosed is a method of inflating an inflatable device, such as a vehicle safety restraint, comprising the step of substantially completely inflating the device with the gaseous composition products of combustion of the pyrotechnic composition, whereby the metallic salt or oxide is substantially prevented from entering the device.
