In an effort to comply with Insensitive Munitions IM criteria together with the expectation of increasing warhead performance against specified targets, two-part energetic binder systems comprising an energetic polymer and plasticizer that offer promise for future use in PBX polymer bonded explosive fills in high-performance, tactical missiles were investigated. Warhead fills within modern missiles such as ASRAAM Advanced Short Range Air-to-Air Missiles typically contain cast-cured PBXs comprising high-energetic loadings in an inert binder matrix. The use of the inert binder, which constitutes around 20 of the final formulation, dilutes the final energy output of the PBX. To this end, several energetic binder formulations were developed that may offer potential use in ASRAAM-type missiles. By use of energetic binder systems comprising polyGLYN and K10 or GLYN oligomer plasticizer, increases in performance parameters were observed. This technical report details the formulation of several PBXs developed to maximize casting density and processibility for potential use in ASRAAM warheads that may offer improved IM properties.
