Preparation, thermal investigation and detonation properties of ε-CL-20-based polymer-bonded explosives with high energy and reduced sensitivity

ε-CL-20 based PBXs with high energy and reduced sensitivity are prepared and characterized for the first time. Their thermal decomposition behaviour, mechanical sensitivities and detonation properties are studied. Results show that the prepared ε-CL-20 based PBXs have a detonation velocity higher than 9100 m·s⁻¹ and acceptable insensitivity. DSC, TG and ARC are used to evaluate the thermal decomposition kinetic parameters, which are in good agreement with those obtained from AKTS thermokinetics program incorporated with TG data.
