RDX-Polyethylene Wax Formulations as Potential Replacements for Tetryl in Fuze Leads, Boosters and Magazines

Abstract

Options for materials suitable for replacement of tetryl in Australian fuzes are reviewed, and a study programme is outlined. In this first stage, a series of RDX/AC629 polyethylene wax formulations from 99.60:0.40 to 93.58:6.37 were prepared via the emulsification technique and assessed for powder impact sensitivity, shock sensitivity and vacuum thermal stability. All were less impact sensitive than granular tetryl. Shock sensitivity was comparable with or lower than that of tetryl, and thermal stability was satisfactory. An unusual shock sensitivity/% TMD trend was noted. The use of higher melting wax AC392 gave no improvement in thermal stability or desensitization to shock. Suggestion for compositions suitable for fuze leads and boosters is made and a programme for further assessment and development outlined.
