Detonating cord (also called detonation cord, detacord, detcord, blasting rope, or primer cord) is a thin, flexible plastic tube usually filled with pentaerythritol tetranitrate (PETN, pentrite).

Gas generators are similar to pyrotechnic fasteners. They are used to generate large amounts of gas, as for ...
