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, anddrying 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.
