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.
Plastic explosive is a soft and hand-moldable solid form of explosive material. Within the field of explosives engineering, plastic explosives are also known as putty explosives [1] or blastics. Plastic explosives are especially suited for explosive demolition. Common plastic explosives include Semtex and C-4. The first manufactured plastic ...
Water-reactive substances [1] are those that spontaneously undergo a chemical reaction with water, often noted as generating flammable gas. [2] Some are highly reducing in nature. [ 3 ] Notable examples include alkali metals , lithium through caesium , and alkaline earth metals , magnesium through barium .
The introduction of water into an explosive is highly undesirable since it reduces the sensitivity, strength, and velocity of detonation of the explosive. Hygroscopicity is a measure of a material's moisture-absorbing tendencies. Moisture affects explosives adversely by acting as an inert material that absorbs heat when vaporized, and by acting ...
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. Variants have different proportions and plasticisers and include Composition C-1, Composition C-2, Composition C-3, and Composition C-4. [1]
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]
The way the explosive material was integrated into the battery pack made it extremely difficult to detect, the source said. Pictures of the walkie-talkies that had exploded showed labels reading ...
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 ...
