We offer C-4 in two (2) varieties, 1.25 lb demolition block and bulk. C-4 detonates with a velocity of approximately 26,000 fps and is made up of approximately 94% RDX. C-4 is composed of explosives, plastic binder, plasticizer to make it malleable, and usually a marker or odorizing taggant chemical. C-4 has a texture similar to modeling clay and can be molded into any desired shape. C-4 is metastable and can be exploded only by the shock wave from a detonator or blasting cap.
Sheet explosives are materials formed by combining an explosive with a "rubberizer"—a flexible binding agent. The resulting compound is cast into a flat sheet which is typically pliable and deformable over a wide range of temperature. Typical products are generally shock-insensitive secondary explosives, requiring a blasting cap or other detonator. Our sheet explosive is comprised of a PETN base.
