In this work, new cyclic nitramine named cis-1,3,4,6-tetranitrooctahydroimidazo-[4,5-d]imidazole (BCHMX) was premixed with insensitive explosives (3-nitro-1,2,4-triazol-5-one, NTO and1,1-diamino-2,2-dinitroethene, FOX) and with two cyclic nitramines (1,3,5-trinitro-1,3,5-triazinane, RDXand, 1,3,5,7-tetranitro-1,3,5,7-tetrazocane, HMX) and bonded by polydimethyl-siloxane (PDMS) binder.Impact and friction sensitivities were evaluated.Detonation read more velocity was measured and the detonationcharacteristics were calculated by EXPLO 5 thermodynamic code.Relative explosive strength wasdetermined by using the ballistic mortar test.

The results showed a great positive influence on the sensitivityof BCHMX due to the addition of the insensitive explosive (NTO, FOX-7) however the performance wasdecreased.On the sheepshead bay boats other side, mixing the nitramines improved the performance with reduction of BCHMXsensitivity.PDMS binder succeed to decrease the sensitivity of all the studied mixtures.
