Low-sensitive high energetic formulations based on HMX were designed by using diaminoazofurazan (DAAzF) as additive. The safety, heat resistance stability and detonation property of formulations were studied by sensitivity test, gap test, DSC, VST and plate dent test. Results show that the addition of fine DAAzF decrease the sensitivity of HMX. By adding 5% DAAzF into HMX based pressing explosives, a low-sensitive high energetic composites is obtained. Its detonation velocity is above 8650 m·s^-1 and its impact sensitivity is 0%.
