초록

A gas generating composition, particularly for inflating devices such as air bag inflators, includes an effective amount of an exploded aluminum powder to both increase the burning rate and lower the composition's pressure exponent.

대표
청구항

[ What is claimed is:] [1.] A gas generating composition comprising a solid solution comprising ammonium nitrate, at least one of guanidine nitrate and aminoguanidine nitrate, a minor amount of polyvinyl alcohol and at least one of potassium nitrate and potassium perchlorate, the gas generating composition further comprising an exploded aluminum powder in an effective amount to increase a burning rate and lower a pressure exponent of the gas generating composition.
