Abstract

The present invention relates to solid propellants for gas generators (gas-generating mixtures), wherein said propellants are mainly intended for use in propelling charges for gas generators used in airbags or seat-belt pre-tensioning devices. The solid propellants for gas generators further include an essentially chemically-inert slag trap which has a high fusion point and a good dispersion, wherein said slag trap acts as an inner filter and globally prevents the formation of powder particles as well as their exit from the housing of the gas generator. A portion of the slag trap having a good dispersion may be used as a carrier substance for catalyst metals.
