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 a fuel, where the binder also acts as the fuel. Preferred oxidizers include those compounds which produce large quantities of infrared radiation when the flare com- position is burned. Such oxidizers include potassium nitrate, cesium nitrate, rubidium nitrate, and combinations of these com- pounds. 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. At the same time, the binder serves to form a com- position which is processible, avoids chunking, and is compatible with the oxidizers used. It has been found that polymer binders which include relatively short carbon chains (1-6 continuous carbon atoms) are preferred. Examples of such polymers include polyesters, polyethers, polyamides and polyamines.
