Thermal analyses of castable plastic bonded explosive (DXC-01) were investigated to estimate the relative long-term thermal stability. The differential thermal analyses and the differential scanning calorimeter indicate no incompatibility In the explosive and binder system. Results of tests indicate plastic bonded explosive (DXC-01) have an explosive and binder that are compatible, produce mild reaction on fast cook off and slow cook off, have excellent thermal stability, and have adequate detonation velocity.
