Abstract
The invention relates to a pyrotechnical composition which is intended both for a hybrid gas-generating material and for a purely pyrotechnical gas-generating material for use in gas-actuated car safety devices, and which comprises a first obligatory constituent in the form of 5-95 wt % of guanyl urea dinitramide and a second obligatory constituent in the form of 5-50 wt % of an oxidizing agent (calculated on the total amount of solids), together with—if it is necessary to increase the rate of burning—a combustion moderator in the form of 0-90 wt % of guanidine dinitramide or up to 10 wt % of finely divided metallic boron, as well as up to 10 wt % of a binder. The pyrotechnical composition according to the invention is characterized e.g. by a low pollutant emission, low smoke formation, and the fact that its rate of burning can be adjusted to suit any type of car safety device by varying the ratio between the constituents within the limits specified in the invention.
