[origin: EP0372893A2] A conducting composition for detonators having insensitivity to one amp of current or one watt of power consisting of 40 to 80 percent by weight of lead styphnate, 2 to 10 percent by weight of carbon black and/or graphite and the balance lead oxide or other exposive or non-explosive material. Firing times of less than eight milliseconds can be achieved where at least one percent of graphite is included in the composition.
