Method for producing propellant compacts

Abstract

The invention relates to a method for producing propellant compacts for use in gas generators for safety devices in motor vehicles by extrusion, comprising the following steps: mixing the constituents of the propellant and stirring the mixture into a paste with a solvent so as to form a plasticizable mass, extruding the plasticizable mass in order to form propellant compacts, and drying the propellant compacts in order to remove the solvent, a thickening agent which increases the viscosity being added to the solvent prior to pasting in a proportion of from 0.1 to 10% by weight, relative to the solvent, and the dried propellant compacts having a density of at least 70% of the theoretical density. The invention further relates to propellant compacts obtainable in accordance with this method.
