Polymer-bonded explosives, also known as Plastic-bonded explosives or simply PBX, are a relatively solid and inflexible explosive form containing a powdered explosive material and a polymer (plastic) binder. These are usually carefully mixed, often with a very thin coating of the polymer onto the powder grains of the explosive material, and ...
Division 4.1: Flammable Solid . Flammable solids are any of the following four types of materials: Desensitized Explosives: explosives that, when dry, are Explosives of Class 1 other than those of compatibility group A, which are wetted with sufficient water, alcohol, or plasticizer to suppress explosive properties; and are specifically authorized by name either in the 49CFR 172.101 Table or ...
In deflagration, decomposition of the explosive material is propagated by a flame front which moves relatively slowly through the explosive material, i.e. at speeds less than the speed of sound within the substance (which is usually still higher than 340 m/s or 1,220 km/h in most liquid or solid materials) [13] in contrast to detonation, which ...
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 ...
Sheet explosives are materials formed by combining an explosive with a "rubberizer" — a flexible binding agent. The resulting compound is cast into a flat sheet which is typically pliable and deformable over a wide range of temperature. Typical products are generally shock-insensitive secondary explosives, requiring a blasting cap or other ...
The explosives factory was later operated by AECI (African Explosives and Chemical Industries). The demand for the product came mainly from the country's vast gold mines, centered on the Witwatersrand. The factory at Somerset West was in operation in 1903 and by 1907 it was already producing 340,000 cases, 23 kilograms (50 lb) each, annually.
A house fire and explosion in New Jersey that killed two men and two young children earlier this month was caused by explosive materials found in the residence, authorities announced Tuesday. The ...
TNT is occasionally used as a reagent in chemical synthesis, but it is best known as an explosive material with convenient handling properties. The explosive yield of TNT is considered to be the standard comparative convention of bombs and asteroid impacts. In chemistry, TNT is used to generate charge transfer salts.
