Composition C-3 was very similar to Composition C-1, but removed the solvent and varied the exact proportions of plasticisers to improve high temperature storage. Its a plastic explosive containing RDX and an inert plasticizer. During the second world war, the British gave plastic explosive to many partisans. H-1703-2 Military Munitions and Explosives of Concern (Public) BLM Manual Handbook iii Rel. 6 cap (one-inch diameter drill hole) over a range of 2-30% by weight nitro-aliphatic hydrocarbon relative to the weight of the dry component at a 50:50 volume ratio of the nitro-aliphatic hydrocarbon to the … liquid DNT and small amount of NT) and nitrocellulose or butyl phthalate and nitrocellulose.[3]. Since 1960 the mixture of C-3 has contained: It is less volatile than C-4 and has less tendency to harden at low temperature. The original use of Nobel 808 supplied by the SOE (see § History) was for sabotage of German installations and railways in Occupied Europe. It suffered from a relatively limited range of serviceable temperatures, and was replaced by Composition C-2 around 1943. This absorbs the energy from the incoming tank round and shields the tank. It is composed of explosives, plastic binder, plasticizer and usually a marker or odorizing taggant chemical, such as 2,3-dimethyl-2,3-dinitrobutane (DMDNB) to help detect the explosive and identify its source. Research on a replacement for C-2 was begun prior to 1950, but the new material, new generation of Composition C (number four, C-4), did not begin pilot production until 1956. [6] It is also the explosive used in HESH anti-tank shells and was an essential factor in the devising of the Gammon grenade. [7] The material was plastic between 0 and 40 degrees C, but was brittle at colder temperatures and gummy at higher temperatures.

The origin of the obsolete term "plastique" dates back to the Nobel 808 explosive introduced to the U.S. by the British in 1940. Consequently, it was replaced around 1944 by Composition C-4. This material consisted of 88.3% RDX and a mineral oil-based plasticiser and phlegmatiser. An early use of plastic explosives was in the warhead of the Petard demolition mortar of the British Armoured Vehicle Royal Engineers (AVRE); said mortar was used to destroy concrete fortifications encountered during Operation Overlord (D-Day). It is used as a blasting powder and a propellant for firearms, rockets, and fireworks. This reduced the toxicity while increasing the concentration of RDX and improving safety of use and storage. There are three classes of C4, with varying amounts of RDX and polyisobutylene. It is a cast-cured explosive composition made from a homogeneous mixture of RDX in a plasticized polyurethane rubber matrix.

Explosive chemicals can be divided into two, as follows : 1. Toy torpedoes containing more than 5 grains of an explosive composition. Semtex became notoriously popular with terrorists because it was, until recently, extremely difficult to detect,2 as in the case of Pan Am Flight 103. Incoming high explosive anti-tank rounds pierce the outer steel plate, then detonate the plastic explosive. Black powder is the name given to the earliest known chemical explosive. Comments, suggestions, or questions on this document should. explosive composition weight explosive Prior art date 2001-02-09 Legal status (The legal status is an assumption and is not a legal conclusion. A casting explosive has a low melt temperature such as TNT, a binary explosive (Cyclotol, RDX/TNT), or a mixture of an explosive held in suspension by a melt carrier (Composition A-3, RDX/Wax). It is so successful that it remains in army service up to the current time without any significant changes. HMX and TATB based explosives at various initial temperatures (1,2). A common commercial use of plastic explosives is for shock hardening high manganese percentage steel,[2] a material typically used for train rail components and earth digging implements. All can be moulded by hand for use in demolition work and packed by hand into shaped charge devices. Firecrackers or salutes exceeding 5 inches in length or 3/4 inch in diameter. Detonating Cord – a flexible cord containing a center core of high explosives used to detonate other explosives. Composition C-3 was very similar to Composition C-1, but removed the solvent and varied the exact proportions of plasticisers to improve high temperature storage. Within the field of explosives engineering, plastic explosives are also known as putty explosives.[1]. In fact, several different compositions have been used throughout history. It was also used for the explosive lenses in the first implosion-type nuclear weapons developed by the United States. It is a yellow, putty-like material. It was standardised as Composition C when introduced to US service. The first manufactured plastic explosive was gelignite in 1875, invented by Alfred Nobel. Common plastic explosives include Semtex and C-4. Experimental Technique Once cured, the material cannot be easily restored to a liquid state. Here are the explosive chemicals examples in daily life: The British used a plastic explosive during World War II as a demolition charge. The original material was developed by the British during World War II, and was used in the Gammon bomb. The two-component explosive composition remains cap sensitive to a No. While Composition C-3 had a much wider serviceable temperature range than Composition C, it could not be s… Black powder, for The Composition C family is a family of related US-specified plastic explosives consisting primarily of RDX. MOD explosives: PE2 (sheet explosive, superseded by SX2). [citation needed]. density/sensitivity test (100% inspection, see 4.5.3.1 & 4.5.3.2). Emulsion explosive composition comprising a matrix of an emulsion of the aqueous dispersion of salt-oxidants - a mixture of ammonium and sodium or calcium nitrate in the environment of the solution of industrial oils and emulsifying composition, a mixture of granulated porous or non-porous ammonium nitrate with diesel fuel and an aqueous solution of sodium nitrite as a sensitizer, wherein as the … 44, : Fuel and Related Compositions, subclasses 506+ for a solid fuel combined with a composition of this class, subclasses 520+ and 530+ for a solid fuel product having a defined shape or structure and subclasses 542+ for a solid fuel composition coated or impregnated for easier ignition. [2] While Composition C-3 had a much wider serviceable temperature range than Composition C, it could not be stored at elevated temperatures. It had the appearance of green plasticine with a distinctive smell of almonds. While few chemicals find use as military explosives (), these can be combined with platiscizers and other materials to create a plethora of formulations. The term composition is used for any explosive material compounded from several ingredients. Variants have different proportions and plasticisers and include composition C-2, composition C-3, and composition C-4.[1]. Explosive, any substance or device that can be made to produce a volume of rapidly expanding gas in an extremely brief period. Based on its sensitivity, it is divided into two : Initiating Explosive; Non-initiating Explosive; The examples of Explosive Chemicals. composition c-4, type ii sara title iii information: waste disposal method: store and handle waste explosives as class a explosives. This explosive composition exhibits a shear thinning rheology. Pursuant to the provisions of section 841(d) of Title 18, United States Code, and 27 CFR 55.23, the Director, Bureau of Alcohol, Tobacco and Firearms, must publish and revise at least annually in the FEDERAL REGISTER, a list of explosives determined to be within the coverage of 18 U.S.C. 2 Explosive Heat of Detonation Heat of Combustion Composition B 1,515 cal./g. The specific explosive, Composition C, was 88.3% RDX and 11.7% non-oily, non-explosive plasticizer. 1-1697 2/1/2006 Military Munitions and Explosives of Concern: A Handbook for Federal Land Managers, with Emphasis on Unexploded Ordnance BLM Handbook [H-1703-2] FWS Handbook 2006 Bureau of Land Management U.S. Cannons, canes, pistols or other devices designed for use otherwise than with paper caps. made. It remained a service item through the Korean War, but had marginal plasticity at the very low temperatures encountered in Korean winters, and was significantly toxic, including by vapour and skin absorption. It is a yellow, putty-like material. [3]:9, The first plastic explosive was gelignite, invented by Alfred Nobel in 1875. The last two compounds (they are very poor explosives) are oily liquids and plasticise the mixture. The velocity of detonation is about 7600 m/s (25,000 feet per second. It is still referred to by this name in France and also by some Americans. Captured SOE-supplied Nobel 808 was the explosive used in the failed 20 July plot assassination attempt on Adolf Hitler in 1944. Composition C2 had a wider temperature range at which it remained plastic, from −30 to 52 degrees C. Composition C2 was replaced by Composition C3, which was a … An explosive perfectly capable of producing an explosion may liberate its energy without producing one. production. Expired - Fee … 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 this application. One of the first reported and tested compositions of C-3 was very similar to earlier Composition C-2 and contained 77% RDX, 3% tetryl, 4% TNT, 1% NC, 5% NT, and 10% DNT. [4] Prior to World War I, the British explosives chemist Oswald Silberrad obtained British and U.S. patents for a series of plastic explosives called "Nitrols", composed of nitrated aromatics, collodion, and oxidising inorganic salts. ), Composition C-3 consists of 77%–85% cyclonite (RDX) and 15%–23% gel made out of liquid nitro compounds (e.g. transport in accordance with the department of transportation regulations for class a explosives. at 2 rpm and 21° C.) the explosive composition has a viscosity from about 50,000 to 300,000 cps, preferably from 75,000 to 200,000 cps and, most preferably from 100,000 to 150,000 cps.
