Pentolite is a high explosive used for military and civilian purposes e.g. warheads and booster charges.

Military pentolite comprises a mixture of 50% PETN and 50% TNT. A 50:50 mixture has a density of 1.65 g/cm3 and a detonation velocity of 7400 m/s. Civilian pentolite sometimes contains a lower percentage of PETN. Civilian pentolite has a detonation velocity of approximately 7,800 metres per second.
