The first plastic explosive was gelignite, invented by Alfred Nobel in 1875. [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. The language of the patents ...
Dynamite is invented by Alfred Nobel by mixing nitroglycerin with silica. It is the first safely manageable explosive stronger than gunpowder. [12] 1867 The use of ammonium nitrate in explosives is patented in Sweden. [13] 1875 Gelignite, the first plastic explosive, is invented by Alfred Nobel. [14] [13] 1884
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.
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 ...
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]
Polymer-bonded explosives, also called PBX or plastic-bonded explosives, are explosive materials in which explosive powder is bound together in a matrix using small quantities (typically 5–10% by weight) of a synthetic polymer. PBXs are normally used for explosive materials that are not easily melted into a casting, or are otherwise difficult ...
Made from plastic, this set includes both measuring spoons and cups, and each one is printed with large, easy to see measurements. ... Explosive Franklin Fire forces thousands to evacuate as 3,000 ...
RDX, PETN, HMX: Very powerful explosives which can be used pure or in plastic explosives C-4 (or Composition C-4): An RDX plastic explosive plasticized to be adhesive and malleable; The above compositions may describe most of the explosive material, but a practical explosive will often include small percentages of other substances.
