Ednatol is a yellowhigh explosive, comprising about 55%ethylenedinitramine (aka Haleite or Explosive H) and 45%TNT by weight. It was developed inthe United States circa 1935 and used as a substitute for Composition B in large general purpose and fragmentation bombs. It has adetonation velocity of approximately 7,400 metres per second. It is a uniform blend with amelting point of 80 °C.^[1]

Ednatol was also used aspentolite is used: in rockets, grenades and high-explosive antitank shells.^[2] Ednatol was cast in the same manner asamatol. The resulting explosive was stable, non-hygroscopic and could be stored for long periods.

Ednatol has no civilian applications. It was developed by the U.S. Army atPicatinny Arsenal exclusively intended for military use and was especially popular during theSecond World War.^[3] It is now an obsolete explosive and therefore unlikely to be encountered, except in legacy munitions andunexploded ordnance.
