Compositions are provided which, when burned, produce significant levels of infrared radiation, but only limited levels of visible radiation. The basic components of the compositions include a binder, an oxidizer, and an organic fuel. Preferred oxidiz- ers include those compounds which produce large quantities of infrared radiation when the flare composition is burned. Such ox- idizers include potassium nitrate, cesium nitrate, rubidium nitrate, and combinations of these compounds. The composition pref- erably includes significant quantities of cesium nitrate as an oxidizer. Selection of the binder is important in order to provide the composition with the desirable characteristics identified above. The binder of the present invention does not produce significant soot when burned. At the same time, the binder serves to form a composition which is processible, avoids chunking, and is com- patible with the oxidizers used. It has been found that polymer binders which include relatively short carbon chains (1-6 continu- ous carbon atoms) are preferred. Examples of such polymers include polyesters, polyethers, polyamides, and polyamines. Sim- ilarly, non-soot producing organic fuels are employed.
