Nylon plastic (polyamides) is available in many compositions, with
Nylon 6/6 and Nylon 6 being the most common. The automotive industry
is the largest user of Nylon or Nylon parts.
- Automotive industry is the largest
user of Nylon due to its low friction, good abrasion resistance,
and the ability to operate without lubrication. Under-the-hood
components are examples of Nylon products.
- Resistance to heat and fuels make
Nylon also suitable for mechanical and electrical hardware.
- Timing sprockets, speedometer
gears, cooling fans, wire connectors, windshield wiper parts,
door-latch hardware, molded fender extensions, steering-column
lock housings, brake fluid reservoirs, and bearings are examples
of automotive parts that are Nylon plastic
- Nylon parts are also used in
business machines, appliances, and industrial equipment.
