Abstract:
An explosive booster cap containing a confined detonable charge, said confinement providing a high degree of water protection for said detonable charge, but which confinement will, when the booster cap is subjected to a fire or excessive heat, be disrupted to allow for outgassing and burning of the detonable charge without explosion. Confinement of the detonable charge is provided by a thermoplastic plug inserted into the open end of the booster cap. The physical properties of the thermoplastic plug permit the plug to deform when heated to a temperature between the decomposition and initiation temperatures of the explosive. The booster cap is slipped over the detonable end of the blasting cap, the resultant combination providing a substantially enhanced explosive output.
