Semtex is a general-purpose plastic explosive containing RDX and PETN. [1] It is used in commercial blasting, demolition , and in certain military applications. Semtex was developed and manufactured in Czechoslovakia , originally under the name B 1 and then under the "Semtex" designation since 1964, [ note 1 ] labeled as SEMTEX 1A , since 1967 ...
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.
PETN is a very powerful explosive material with a relative effectiveness factor of 1.66. [2] When mixed with a plasticizer, PETN forms a plastic explosive. [3] Along with RDX it is the main ingredient of Semtex. PETN is also used as a vasodilator drug to treat certain heart conditions, such as for management of angina. [4] [5]
This is a compilation of published detonation velocities for various high explosive compounds. Detonation velocity is the speed with which the detonation shock wave travels through the explosive.

The jet cuts any material in its path, to a depth depending on the size and materials used in the charge. Generally, the jet penetrates around 1 to 1.2 times [56] the charge width. For the cutting of complex geometries, there are also flexible versions of the linear shaped charge, these with a lead or high-density foam sheathing and a ductile ...
