Ednatol is a yellow high explosive, comprising about 58% ethylenedinitramine (aka Haleite or Explosive H) and 42% TNT. It was developed in the USA circa 1935 and used as a substitute for Composition B in large general purpose and fragmentation bombs. It has a detonation velocity of approximately 7,400 metres per second.

Ednatol was also used as Pentolite

Pentolite

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...

. The resulting explosive was stable, non-hygroscopic and could be stored for long periods.

Ednatol has no civilian applications. It was exclusively intended for military use and was especially popular during the Second World War. It is now an obsolete explosive and therefore unlikely to be encountered, except in of legacy munitions and unexploded ordnance

Unexploded ordnance

Unexploded ordnance are explosive weapons that did not explode when they were employed and still pose a risk of detonation, potentially many decades after they were used or discarded.While "UXO" is widely and informally used, munitions and explosives of...
