Abstract: A pyrotechnic charge for the rapid opening of a bursting closure of a prerized gas container, particularly for transferring the pressurized gas into another, lower pressure area, e.g. for air bags in motor vehicles, comprises an energy carrier to crystalline nitra-mines, preferably RDX or HMX, and an energy-rich, reactive polymer as the binder, e.g. di- or poly-functional glycidyl-azide polymer (GAP). Such a charge leads to a rapid build-up of the opening pressure and produces adequate heat for avoiding cooling of the gas during the overflow.
