Nylatron™ 66 SA PA66 AE (Aerospace) unmodified nylon shapes are characterized by their superior combination of strength and toughness. Compared to other unmodified nylon grades, Nylatron™ 66 SA AE PA66 components possess superior mechanical strength, stiffness and wear resistance. Due to these properties and its FDA 21 CFR § 177.1500 compliance, Nylatron™ 66 SA PA66 AE is often specified for screw machined electrical insulators, bushings, bearings, gears, roller wheels, star wheels and seals, especially in aerospace applications.
