Detonating Fuse is a flexible cord containing a uniform core load of PETN that ensures positive initiation of cap-sensitive explosives along the entire length of the fuse. This high explosives core is protected to with-stand physical abuses and exposure to extreme temperatures. Detonating fuse is relatively insensitive to detonation by friction, shock or electric discharge and requires a proper initiation for detonation.

It makes efficient primer and booster that detonate at a very High Velocity Detonation and Temperature. These qualities, together with high density produces great Detonation pressure. The booster can be stored for long period of time, as it contain no liquid ingredients and can be operated easily.
Cast Boosters are available in 100grams, 250grams, 400 grams and 500grams.
Cast Boosters contain no Nitro-Glycerin and therefore are less sensitive to shock and friction .
Cast Boosters have long storage life.
Convenient to use and assemble no prickers are required.
Cast Boosters contain no headache causing ingredients.

The most common use of PETN is as an explosive with high brisance. It is more difficult to detonate than primary explosives, so dropping or igniting it will typically not cause an explosion (at atmospheric pressure it is difficult to ignite and burns relatively slowly), but is more sensitive to shock and friction than other secondary explosives such as TNT or tetryl. Under certain conditions a deflagration to detonation transition can occur.It is rarely used alone, but primarily used in booster and bursting charges of small caliber ammunition, in upper charges of detonators in some land mines and shells, and as the explosive core of detonation cord.PETN is the least stable of the common military explosives, but can be stored without significant deterioration for longer than nitroglycerin or nitrocellulose.
