The most common use of PETN is as an explosive with high brisance. It is used in the manufacture of detonating fuse, detonators and plastic explosives. If phlegmatized with a small amount of wax and pressed, it may be used to produce boosters and fillings for smaller caliber projectiles. PETN can also be incorporated into gelatinous, industrial explosives.
