EXPLOSIVES ENGINEERING rubberized

Formaldehyde (CH20) is an important compound in the synthesis of various chemicals on an industrial scale. One of the first industrial applications was in the production of artificial Indigo. The variety of end products produced from formaldehyde include resins or glues (produced by the condensation of formaldehyde with urea, phenol, or melamine) as well as rubber, paper, fertilizers, explosives, engineering plastics, and specialty chemicals like acrolein, methacrylic acid, methyl methacrylate, etc. Because it is nearly impossible to handle in its pure gaseous form, formaldehyde is almost exclusively produced... 

Originally, equipment was made largely from wood or gun-metal and often rubber lined. These materials give the lowest hazards from friction with explosives. Nowadays, improved standards of engineering and of design have made it possible to employ stainless steel and plastics in the construction of explosive machinery with considerable increase in mechanical efficiency. In this way not only can processes be carried out more rapidly, but the quantity of explosive present at any time is reduced, with consequent increase in overall safety. 

Butane is found in exhausts of gasoline engines and in waste disposal sites. Butane as a gas is highly inflammable and explosive pure butane has several applications in industries and processing associated with aerosol propellants, fuel source, solvents, rubber, plastics, food additive, and refrigeration. Occupational exposure to liquefied butane by direct contact results in severe adverse effects (e.g., bums or frostbite to skin, eyes, and mucous membrane, as well as CNS depression).

In the First World War the very air had become a resource for explosives, as nitrogen was snatched from the atmosphere and processed. In that war nature had failed the German war effort, and science had been forced to substitute itself. Without rubber there could be no tyres, no electrical insulation, no balloon fabrics, no hoses, no engine packing, all necessary for industrial,... 

Du Font s major contribution to the country s war effort in World War 1 was the manufacture of explosives. By the time World War 11 erupted, explosives was just one of the many Du Pont products needed in the war effort. The insatiable appetite of the war machine imposed numerous demands on technical personnel to build new process lines (over 50 plants were built) in record time and to develop specialty products by yesterday. Chemical engineers played a key role in meeting these demands. Since natural rubber was no longer available, plants to manufacture synthetic rubber such as neoprene had to be built. Rayon and nylon were used in tire cord. Industries producing combat equipment needed heavy chemicals. The emergence of air power required special chemical materials such as plastic enclosures.
