Pentolite
Pentolite is a composite high explosive used for military and civilian purposes, e.g., warheads and booster charges. It is made of pentaerythritol tetranitrate phlegmatized with trinitrotoluene by melt casting.
The most common military variety of pentolite is a mixture of 50% PETN and 50% TNT. This 50:50 mixture has a density of 1.65 g/cm3 and a detonation velocity of 7400 m/s.
Pentolite is a common explosive for cast boosters for the blasting work. Civilian pentolite may contain a lower percentage of PETN, e. g. around 2%, 5% or 10%. These civilian pentolites have a detonation velocity of about 7,800 metres per second.
