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 (PETN) phlegmatized with trinitrotoluene (TNT) by melt casting.[1]
The most common military variety of pentolite (designated "Pentolite 50/50") is a mixture of 50% PETN and 50% TNT.[1] (Unlike other compound explosives, the number before the slash is the mass percentage of TNT and the second number is the mass percentage of PETN.) 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 (as in mining).[2][3] Civilian pentolite may contain a lower percentage of PETN, e. g. around 2% ("Pentolite 98/2"), 5% ("Pentolite 95/5") or 10% ("Pentolite 90/10"). These civilian pentolites have a detonation velocity of about 7,800 metres per second.
