Preparing C-4 explosiveC-4 or Composition C-4
is a common variety of military plastic explosive. The term composition is used for any stable explosive, and "Composition A" and "Composition B" are other known variants. C-4 is made up of explosive, plastic binder, plasticizer and, usually, marker or taggant chemicals such as 2,3-dimethyl-2,3-dinitrobutane (DMDNB) to help detect the explosive and identify its source. As with many plastic explosives, the explosive material in C-4 is RDX (also known as cyclonite or cyclotrimethylene trinitramine) which makes up around 91% of the C-4 by weight. The plasticizer is di(2-ethylhexyl) or dioctyl sebacate (5.3%), and the binder is polyisobutylene (2.1%). Another plasticizer used is dioctyl adipate (DOA). A small amount of SAE 10 non-detergent motor oil (1.6%) is also added. C-4 detonates at about 26,400 fps (8,050 meters per second).
