  • Pressable plastic-bound explosive composition
    Patent number: 7857922
    Abstract: The present invention relates to pressable explosive compositions with enhanced sensitivity characteristics and processability. The explosive compositions are based on crystalline explosive crystals of 1,3,5-trinitro-1,3,5-triazacyclohexane (RDX) Type I alone or in combination with a smaller percentage of 1,3,5-tetranitro-1,3,5,7-tetrazacyclooctane (HMX) where the crystals are coated with a binder system consisting of a polyacrylic elastomer to which a plasticizer is added. These explosive compositions are produced in a so-called water-slurry process where the explosive crystals are washed in water whereupon a solution of the binder system is added. After the admixture the solvent is distilled off and the coated product is isolated by filtering.

  • Pressable explosive composition
    Publication number: 20060060273
    Abstract: The present invention relates to low-sensitivity, pressable, aluminum-containing explosive compositions and a method of producing them. The compositions comprise between 45 and 95% by weight explosive crystals, between 5 and 55% by weight passivated aluminum and a binder that is chosen such that the composition satisfies the requirements for low-sensitivity explosives (IM requirements). Due to the fact that the aluminum is passivated, the composition can be produced by the use of a well-known water slurry process.
