Cyclotetramethylene tetranitramine, a high explosive used in the core loading of shock / signal tube and in high temperature applications.

HMX, also called octogen, is a powerful and relatively insensitive nitroamine high explosive, chemically related to RDX

The molecular structure of HMX consists of an eight-membered ring of alternating carbon and nitrogen atoms, with a nitro group attached to each nitrogen atom. Because of its high molecular weight, it is one of the most potent chemical explosives manufactured
