It is also waterproof. There are visual differences between Semtex and other plastic explosives, too: while C-4 is off-white in colour, Semtex is red or brick-orange. The new explosive was widely exported, notably to the government of North Vietnam, which received 14 tons during the Vietnam War.
A C-4 charge packed onto a marine anchor chain. Plastic explosives are especially suited for explosive demolition of obstacles and fortifications by combat engineers as they can be easily formed into ideal shapes for cutting structural members and have a high enough velocity of detonation and density for metal cutting work.
[7] [8] [9] Depending on its intended usage and on the manufacturer, there are differences in the composition of C-4. For example, a 1990 U.S. Army technical manual stipulated that Class IV composition C-4 consists of 89.9±1% RDX, 10±1% polyisobutylene, and 0.2±0.02% dye that is itself made up of 90% lead chromate and 10% lamp black .

The Composition C family is a family of related US-specified plastic explosives consisting primarily of RDX.All can be moulded by hand for use in demolition work and packed by hand into shaped-charge devices.
PBX system numbers start around 9000 and use numerous scattered numbers between there and 9700. ... C4 (Now-obsolete) Composition C; Semtex; PE-4; Rubberized
RDX is often used in mixtures with other explosives and plasticizers or phlegmatizers (desensitizers); it is the explosive agent in C-4 plastic explosive and a key ingredient in Semtex. It is stable in storage and is considered one of the most energetic and brisant of the military high explosives, [2] with a relative effectiveness factor of 1.60.
Explosive Flavor. For a long time, it felt like there were maybe three energy drink brands. Today, there are more than you can count, and one of the most explosive entries into the energy drinks ...
Atop the thin layer is placed an explosive. At one end of the layer of explosive, the explosion is initiated. The two metallic layers are forced together at high speed and with great force. The explosion spreads from the initiation site throughout the explosive. Ideally, this produces a metallurgical bond between the two layers.
