IMX-101 is a high-performance insensitive high explosive composite mixture developed by BAE Systems and the United States Army to replace TNT in artillery shells.
For example, it is believed that a training incident in Nevada which killed seven Marines would not have occurred with the new explosive.
[8][9][10] Trace amounts of N-methyl-p-nitroaniline (MNA) are included in some formulations to aid in processing.
[13] The performance of PAX-28, a thermobaric, containing a mixture of RDX, DNAN, Al, AP and MNA was found to have an indoor explosive equivalency factor of 1.62 when compared to Composition B.
[citation needed] Like Composition B, IMX formulations are melt-castable without thermal degradation, and are thus processed into munitions by a melt pour process starting with a batch melt kettle heated by a steam heat exchanger.
