FOX-7, or 2,2-Dinitroethene-1,1-diamine, is a novel high explosive with promising properties as an IM ingredient. Its detonation performance, in pure form, is quite similar to that of RDX, but with sensitivity to various stimuli lower than that of TNT. The FOX-7 molecule is chemically, thermally and mechanically very stable and shows excellent compatibility with all substances that it was tested against, including isocyanates, which often are difficult to combine with other explosive substances. Thermochemical calculations show that PBX's based on FOX-7 and energetic binders can serve as a replacement of Comp B even at rather low solid loadings. A castable formulation of FOX-7 and polyGlyN was made. Small-scale safety tests show that the compositions are not sensitive to friction and the thermal stability at 65°C is excellent. Large-scale detonation tests and small-scale slow cook-off tests show that the FOX-7 based PBX does not detonate at a diameter of 25 mm. Upon slow heating (3.3°C/hour) it ignites at 150°C and burns without damage to the container or the surroundings.
