A timing element for an initiator is made from a reactive polymeric material such as, e.g., a glycidyl azide polymer. The reactive polymeric material may include pulverulent oxidizer additives, such as ammonium, perchlorate and/or ferric oxide. The oxidizer additives are used to increase the rate of reaction and the output spark of the polymer material. The timing element serves to delay the travel of an initiation signal between an input, such as a signal transmission input line, and an explosive output charge, for a predetermined period of time, usually about 5 to about 10,000 milliseconds, e.g., about 9 to about 9600 milliseconds.

A gas-impermeable sealer element () for a detonator or other explosive initiation device includes a non-reactive sleeve () having a channel () formed therein. A reactive material strip () is sealed within the channel for transmission of an explosive's initiation signal through the sealer element (), either alone or in cooperation with transfer charges located at the input and/or output end of the non-reactive sleeve (). The reactive material strip () comprises a reactive metal wire or other substrate () having on one or both sides thereof a layer of reactive material (), either reactive metal foils which react exothermically when ignited, or a deposited fuel-oxidizer reactive material. The reactive materials, upon being energized, react exothermically in the absence of atmospheric oxygen or other extraneous oxidizer and so may be encapsulated, sealed or otherwise isolated from the atmosphere in use.

A booster explosive () comprises a canister body within which is a cap well () having disposed therein a detonator (). A protective sleeve () encloses the cap well () except for that portion of the cap well, the active portion (), which encloses the explosive end section () of detonator (). The protective sleeve serves to attenuate the force of shock waves from nearby prior explosions acting on the detonator (). An annular air space () may be provided between protective sleeve () and cap well () to further attenuate the force of such shock waves. Attenuation of the shock waves reduces the likelihood of damage to detonators () by prior nearby explosions.
