The physical and chemical properties of a new energetic polymer adhesive (ATP28) were analyzed. Adding four plasticizers into ATP28 respectively,the plasticities of the explosive mixtures containing ATP were studied by viscosity tests. Comparing the detonation velocities of the explosive with ATP or HTPB as its adhesives,the effect of the ATP28 on the explosion energy was studied. The experimental results show that the viscosity of the energetic adhesive with DOA is decreased by 97%. Temperature plays an important part in the viscosity system. Detonation velocity of explosive formulation containing ATP28 is 7350 m·s^-1. It is shown that detonation velocity can be improved evidently by adding ATP28.
