A Plastic Bonded Explosive (PBX's) is mainly composed of nitramine explosive and polymer binder.  A great number of serious applications of PBX require the good adhesion between nitramine crystals and the binder, which depends on the surface characteristics of a filler and binder.  In the pursuit of the better design to achieve the enhanced adhesion, profound knowledge of the surface and interfacial characteristics of explosive and binder should be exploited.  In this work, the influences of physicochemical properties between RDX and binders such as interfacial tension(γSL), latent heat(Qm), and density(ρ) on impact sensitivity of PBX were investigated.  The major contribution factor to impact sensitiveness of PBX was the interfacial tension, compact to other surface properties.
