  • Precompression resistant emulsion explosive
    Patent number: 5507889
    Abstract: An emulsion explosive composition having improved resistance to precompression desensitization comprising an emulsion explosive matrix and a high level of a low strength microspheres. Preferably, the microspheres having a crush strength of between 100 and 400 psi, and are present in at least 4% by weight of the formulation. Accordingly, the present invention allows the use of a more standard (and usually less expensive) microspheres in the production of a precompression desensitization-resistant emulsion explosive. Further, the emulsion explosives of the present invention would permit emulsion explosives, in general, to be utilized in a wider range of applications.
