A flame extinguishing pyrotechnic which flamelessly deflagrates to produce primarily nitrogen, carbon dioxide, and a fluoroolefin. The flame extinguishing characteristic is achieved by reducing the content of oxygen proximate the deflagration as well as through the flame suppressing properties of particular fluoroolefins. The pyrotechnic composition contains an azide binder such as glycidyl azide polymer GAP, an azide plasticizer, a solid tetrazole, and a perfluorocarboxylic acid salt. This composition is cured to a rubbery composite by the addition of an isocyanate.
