ABSTRACT PYROTECHNIC SHEET MATERIAL The invention provides pyrotechnic sheet material comprising a substrate of porous, vapour-permeable oxidizing polymeric film, for example a halogenopolymeric film, having a layer of oxidizable material for example magnesium, on at least part of its surface, the substrate and the oxidizable material being conjointly capable of reacting together on ignition. Advantageously at least part of the oxidizing material is accommodated within the polymer pores. The pyrotechnic sheet material burns faster than material comprising solid polymeric film.
