  • Patent number: 4369708
    Abstract: A delay blasting cap having improved uniformity and predictability of delay time, and less susceptible to timing change as a result of a change in the medium or temperature surrounding the cap, has a polyolefin or polyfluorocarbon carrier capsule or tube for the delay charge, and preferably a rigid metal capsule holding the delay charge in place. Preferably, the delay carrier is a polyethylene capsule, which inhibits the priming charge from penetrating into the delay charge during the assembling of the cap.
