Nylon (PA)

Nylon (PA) is a synthetic thermoplastic linear polyamide that was first produced in 1935 by American chemist Wallace Carothers who was then working at the DuPont research facility in Delaware. Nylon is used for many injection molded parts for vehicles and mechanical equipment. PA is often used in gears, bushings, and plastic bearings because of its inherent low-friction properties. PA’s high performance in mechanical/chemical/thermal properties make it a good choice for parts that are susceptible to a lot of wear.
