Du Pont ALATHON® helps solve piping and packaging problems in chemical industries Du Pont "Alathon" polyethylene res in is inert to many chemicals used in industry. Hydrochloric, sulfuric and hydrofluoric acids, in concentrated solutions, can be shipped or stored in carboys or bottles of "Alathon." "Alathon" is odorless, tasteless and non-toxic. It has a low watervapor transmission rate. "Alathon" is tough and flexible over a wide temperature range. In some cases, "Alathon" retains its form unstressed in boiling water. "Alathon," with a specific gravity of 0.92, is one of the lightest plastic resins commercially available today.
Combination of Properties Because of an unusual combina tion of properties—high chemical re sistance, toughness and flexibility through a wide temperature range— "Alathon" presents possibilities for applications in many industrial fields. Among the important industrial uses for "Alathon" are pipe and fittings for water and chemical process lines. Du Pont "Alathon" polyethylene resin is used as packaging material in such forms as film, bottles, clo sures, liners for fiber and metal drums, and carboys.
Flexible Bellows of TEFLON Assures Maximum Service Life Where applications are toughest in the chemical processing industry, parts of Du Pont "Teflon" tetrafluoro ethylene resin assure dependable operation. For "Teflon" is not at tacked by any chemicals normally encountered—only molten alkali met als, and fluorine at elevated temper atures and pressures affect "Teflon." And, conversely, "Teflon" will not contaminate the products in contact with it. Operating temperature range is from —450°F. to 500°F. This wide ranges coupled with the chemical in ertness of "Teflon," provides new opportunities for designers of proc ess equipment. Consider the flexible bellows of Du Pont "Teflon" tetrafluoroethylene resin fabricated by Crane Packing Company of Chicago, Illinois. These bellows are designed for heavy-duty applications—as vibration dampeners, expansion joints, flexible con nectors—and the manufacturer re ports that French gasket-type flanges assure maximum sealing efficiency. Crane Packing Company has devel oped a new convolution form, they report, which assures great strength, long service life and maximum flex ibility. The bellows are formed at
