Insensitive explosive mixtures of octogen, hexogen crystals have a bimodal grain composition comprising coarse grain of 280-360 μm and fine grain of 15-45 μm and a binder system HYTEMP® and DOA using a conventional solvent. Explosive mixtures are obtained, which are of differing sensitivity and which in the GAP test attain the classification of little sensitivity in accordance with STANAG 4170.
Pressed insensitive explosive mixtures in which explosive crystals are bound by a binder system, characterised in that a bimodal grain composition comprising coarse-grain and fine-grain explosive crystals is bound by a binder system comprising a plasticiser and HYTEMP®, and is produced in the solvent process.

The invention relates to pressed insensitive explosive mixtures as set forth in the classifying portion of claim 1.
Explosive mixtures of that kind are known from DE 199 55 657 A1. Explosive crystals such as hexogen, octogen and CL20 have a binder matrix comprising sonochemically produced very fine TATB (1,3,5-triamino-2,4,6-trinitrobenzene). That provides that the explosive was classified in accordance with the GAP test as involving little sensitivity. The pressing force required is >2 kbars.
The object of the present invention is to propose insensitive explosive mixtures which are of the utmost simplicity to produce and which, with the lowest possible pressing pressures of markedly <1 kbars, acquire of the theoretical maximum density >98%, and therefore have a very high pressed body density.
