Octol

Octol is a melt-castable, high explosive mixture consisting of HMX and TNT in different weight proportions.

Two formulations are commonly used: Given that HMX has a much higher detonation velocity than TNT (over 2,000 metres per second faster) and forms the main part of this explosive blend, the brisance characteristics of Octol can be inferred.

The applications of Octol are generally military; e.g., shaped charges and warheads that are used in guided missiles and submunitions.

The advantage of Octol is that it significantly reduces the size and weight of the explosive charge required.

This in turn results in a higher velocity missile with a longer range and shorter flight time.
