The response of the HMX-based material PBXN-9 to thermal insults: Thermal decomposition kinetics and morphological changes

▶ PBXN-9 is more sensitive to elevated temperatures than similar HMX-formulations. ▶ Plasticizer volatility affects morphology and structure parts after mild heating. ▶ Binder and plasticizer do not affect the HMX decomposition kinetics. ▶ Parts heated above the HMX β-δ transition undergo significant changes in morphology.
