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.
C-4 or Composition C-4 is a common variety of the plastic explosive family known as Composition C, which uses RDX as its explosive agent. C-4 is composed of explosives, plastic binder, plasticizer to make it malleable, and usually a marker or odorizing taggant chemical.
Marzouk was found to be carrying 9.5 pounds (4.3 kg) of Semtex, several packets of TNT, 10 detonators, and an electronic timer—a so-called MST-13 timer—with the word Mebo printed on it. DERA's timer fragment, which was subsequently designated as PT/35(b), would eventually lead detectives via its Swiss manufacturer to Abdelbaset al-Megrahi .

Pentaerythritol tetranitrate (PETN), also known as PENT, pentyl, PENTA (ПЕНТА, primarily in Russian), TEN (tetraeritrit nitrate), corpent, or penthrite (or, rarely and primarily in German, as nitropenta), is an explosive material.
An example is with Semtex, which now is made with DMDNB added as a detection taggant. [16] DMDNB is a common taggant as dogs are sensitive to it. In the UK, the relevant legislation is the Marking of Plastic Explosives for Detection Regulations 1996. [17]
Unsintered cold pressed liners, however, are not waterproof and tend to be brittle, which makes them easy to damage during handling. Bimetallic liners, usually zinc-lined copper, can be used; during jet formation the zinc layer vaporizes and a slug is not formed; the disadvantage is an increased cost and dependency of jet formation on the ...
