Mg/Teflon®/Viton (MTV) flares are the pyrotechnic compositions used in infrared decoys to protect aerial targets from IR-guided missiles. In this study, the influence of formulation changes on the burning time, and on the time to reach the required level of intensity of infrared radiation was examined. An ignition, in particular the quantity of ignition mixture used, and the ignition surface has a significant influence on the tested parameters. For charges with a density of 1.7 g/cm3 and a mass of approx. 40 g, it was possible to obtain the required rise time and intensity of radiation after applying about 5 g of the igniting mixture. The ratio of the grooved area, with the ignition mixture on the lateral surface of the pellet, to the total lateral surface of the pellet was approx. 0.6.
