Miscellaneous Engineering Applications

In addition to specialized applications of reinforced plastics, as discussed in Chapters 7 and 8, plastics are used in a wide range of engineering applications, such as gears and bearings. Some of these applications are listed below. 

General engineering applications are reviewed in Table 9.1. These include gears, bearings, valves, seals, pump impellers, piston rings, pipes and hoses, compression valves, plugs, and wear pads.

Engineering applications for plastics include mechanical units imder stress, low friction components, heat and chemical resistant units, electrical parts, housings, high Hght transmission applications, building construction functions, and many miscellaneous uses. 

Miscellaneous Applications. There are many such uses, some of which will be questioned as engineering. Some of these applications include building construction, luggage, safety-helmets, seating, kitchen utensils, rope and strapping, shoe parts, rollers, furniture, and even dentures. This list can go on almost indefinitely and the plastics used, reflecting desired properties, will vary widely. 

A very large catalogue of miscellaneous applications for engineering plastics could be assembled, extending into every piece of electrical equipment. A few generalizations are all that can be given here ...
