A C-4 plastic explosive. C-4 or Composition C-4 is a common variety of military Plastic explosive.

Plastic explosive (or the obsolete term plastique) is a specialised form of explosive material. An explosive material is a material that either is chemically or otherwise Energetically unstable or produces a sudden expansion of the material usually accompanied It is soft and hand malleable and may have the added benefit of being usable over a wider temperature range than pure explosive - (often made of a military used material called semtex or a slightly less effective and combustive material called C-4). Semtex is a general-purpose Plastic explosive containing RDX and PETN. Plastic explosives are especially suited for explosive demolition as they can be easily formed into the best shapes for cutting structural members, and have a high enough velocity of detonation and density for metal cutting work. Demolition is the opposite of Construction: the tearing-down of Buildings and other Structures It contrasts with deconstruction Explosive velocity is the Velocity at which the shockwave front travels through a detonated Explosive. The density of a material is defined as its Mass per unit Volume: \rho = \frac{m}{V} Different materials usually have different They are generally not used for ordinary blasting as they tend to be significantly more expensive than other materials that perform just as well in that field. Rock blasting is the controlled use of Explosives to excavate or remove rock. Also, when an explosive is combined with a plasticizer, its power is generally lower than when it is pure. Plasticizers are additives that increase the Plasticity or Fluidity of the material to which they are added these include plastics cement concrete wallboard and

History

The first plastic explosive was Gelignite, invented by Alfred Nobel in 1875. Gelignite, also known as blasting gelatin, is an Explosive material consisting of Collodion - Cotton (a type of Nitrocellulose (21 October 1833 Stockholm, Sweden – 10 December 1896 Sanremo, Italy) was a Swedish chemist engineer innovator armaments manufacturer Year 1875 ( MDCCCLXXV) was a Common year starting on Friday (link will display the full calendar of the Gregorian calendar (or a Common

One of the simplest plastic explosives was Nobel’s Explosive No. 808, also known as Nobel 808 (often just called Explosive 808 in the British Armed Forces during the Second World War), developed by the British company Nobel Chemicals Ltd well before World War II. The Armed forces of the United Kingdom, commonly known as the British Armed Forces or Her Majesty's Armed Forces, and sometimes legally the Armed Forces World War II, or the Second World War, (often abbreviated WWII) was a global military conflict which involved a majority of the world's nations, including Nobel Enterprises is a chemicals business based at Ardeer, near to near Stevenston in North Ayrshire, Scotland. World War II, or the Second World War, (often abbreviated WWII) was a global military conflict which involved a majority of the world's nations, including It had the appearance of green plasticine with a distinctive smell of almonds. Green is a Color, the perception of which is evoked by light having a spectrum dominated by energy with a Wavelength of roughly 520–570- nm. Plasticine, a brand of Modelling clay, is a Putty -like modelling material made from Calcium salts Petroleum jelly and aliphatic acids The Almond ( Prunus dulcis, syn Prunus amygdalus Batsch Amygdalus communis L During World War II it was extensively used by the British Special Operations Executive (SOE) for sabotage missions. World War II, or the Second World War, (often abbreviated WWII) was a global military conflict which involved a majority of the world's nations, including The Special Operations Executive ( SOE) (sometimes referred to as "the Baker Street Irregulars " after Sherlock Holmes ' fictional group of helpers It is also the explosive used in HESH anti-tank shells. Anti-tank refers to any method of combating military Armored fighting vehicles notably Tanks The most common anti-tank systems

During and just after World War II a number of new RDX-based explosives were developed, including Compositions C, C2, and eventually C3. Cyclotrimethylenetrinitramine, also known as RDX, cyclonite, hexogen, and T4, is an Explosive Nitroamine widely used Together with RDX these incorporate various plasticisers to decrease sensitivity and make the composition plastic. Plasticizers are additives that increase the Plasticity or Fluidity of the material to which they are added these include plastics cement concrete wallboard and

The origin of the obsolete term plastique dates back to the Nobel 808 explosive introduced to the US by the British in 1940. The United Kingdom of Great Britain and Northern Ireland, commonly known as the United Kingdom, the UK or Britain,is a Sovereign state located The samples of explosive brought to the USA by the Tizard Mission had already been packaged by the SOE ready for dropping to the French Resistance and were therefore labelled in French, as Explosif Plastique. The Tizard Mission officially the British Technical and Scientific Mission was a British delegation that visited the United The Special Operations Executive ( SOE) (sometimes referred to as "the Baker Street Irregulars " after Sherlock Holmes ' fictional group of helpers The French Resistance is the collective name used for the French Resistance movements which fought against the Nazi German It is still referred to by this name in France, and also by a few Americans. This article is about the country For a topic outline on this subject see List of basic France topics. However, most English-speaking users refer to it either by the actual label printed on the packaging (e. g. C-4 or Semtex) or as plastic explosive. C-4 or Composition C-4 is a common variety of military Plastic explosive. Semtex is a general-purpose Plastic explosive containing RDX and PETN.

C3 was effective but proved to be too brittle in cold weather. In the 1960s it was replaced by C-4, also using RDX but with polyisobutylene and di(2-ethylhexyl)sebacate as the binder and plasticizer. C-4 or Composition C-4 is a common variety of military Plastic explosive. Cyclotrimethylenetrinitramine, also known as RDX, cyclonite, hexogen, and T4, is an Explosive Nitroamine widely used Butyl rubber &mdashalso known as polyisobutylene and PIB (C4H8n is a Synthetic rubber, a Homopolymer of

Semtex was also developed in the 1960s by Stanislav Brebera by mixing of RDX with PETN and then adding binders and stabilizers. Semtex is a general-purpose Plastic explosive containing RDX and PETN. Cyclotrimethylenetrinitramine, also known as RDX, cyclonite, hexogen, and T4, is an Explosive Nitroamine widely used Pentaerythritol tetranitrate ( PETN, also known as pentrite, or rarely and primarily in German as nitropenta) is one of the most powerful high explosives

Some terrorist groups have also used plastic explosives, especially Semtex and C-4. Terrorism is the systematic use of terror especially as a means of coercion Semtex is a general-purpose Plastic explosive containing RDX and PETN. In October 2000, terrorists used C-4 to attack the U.S.S. Cole, killing 17 sailors^[2] In 1996, terrorists used C-4 to blow up the Khobar Towers U.
