Improved, multiphase, high performance, high energy, extrusion cast explosive compositions, comprising, a crystalline explosive material; an energetic liquid plasticizer; a urethane prepolymer, comprising a blend of polyvinyl formal, and polycaprolactone; a polyfunctional isocyanate; and a catalyst are disclosed. These new explosive compositions exhibit higher explosive content, a smooth detonation front, excellent stability over long periods of storage, and lower sensitivity to mechanical stimulants.
1. A multiphase extrusion cast explosive composition comprising: a crystalline explosive material; an energetic liquid plasticizer; a urethane prepolymer mixture, comprising a blend of polyvinyl formal and polycaprolactone; a polyfunctional isocyanate; and a catalyst. 2. The composition of claim 1 wherein said crystalline explosive is selected from the group consisting of octahydro-1,3,5,7-tetranitro-1,3,5,7-tetrazocine, hexahydro-1,3,5-trinitro-1,3,5-triazene, 2,2-bis[(nitro oxy)methyl]-1,3-propanediol-dinitrate, and 2,4,6-trinitro-1,3,5-benzen...
