Abstract (en)

[origin: WO0226662A1] The invention concerns a slow combustion composition for long pyrotechnic delays. It comprises an oxidant of the perchlorate type in a mass percentage ranging between 75 and 91 %, a reducer selected among aromatic hydrocarbons in a mass percentage ranging between 5 and 20 %, 0 to 6 % by volume of a binder and 0 to 5 % by volume of a nanometric silica powder. The invention is useful for making cords or wicks for combustion rate delays of the order of mm/s.
