PETN

PETN (pentaerythritol tetranitrate, penthrite) is a white crystalline substance, non-hygroscopic and insoluble in water (readily soluble in acetone), and can be readily pressed to a density of 1.6. In terms of sensitivity to mechanical effects, PETN is among the most sensitive of all practically used high explosives. It detonates when struck by a bullet. PETN burns vigorously with a white, soot-free flame. During burning, combustion may transition to detonation. PETN does not chemically react with metals. PETN is used for manufacturing detonating cord and loading detonator caps, and in a phlegmatized state it may be used for manufacturing booster (intermediate) detonators, plastic explosives, and for loading certain munitions. Phlegmatized PETN is tinted pink or orange.
