In an effort to comply with Insensitive Munitions IM criteria while minimising any reduction in performance, two part energetic binder systems which comprise an energetic polymer and an energetic plasticiser, are being developed for future use in PBX polymer bonded explosive fills in tactical missiles. Energetic binder systems confer energy output increases over conventional inert binder systems and are thus of interest to the ADF. Under a collaborative agreement with the UK, the ADF has received a new energetic plasticiser, GLYN oligomer, which promises to provide improvements such as higher energy output, good mechanical properties and low plasticiser exudation. This report serves to characterise the GLYN oligomer and examine its plasticising properties. Furthermore, comparison of migration data of the oligomer and other plasticisers show that the GLYN oligomer is less likely to exude from PBX than other conventional plasticisers, thereby increasing the in- service life.
