Ertalon™ 6 XAU+ PA6 is a heat-stabilized cast nylon grade with a very dense and highly crystalline structure. Compared to conventional extruded or cast nylons, Ertalon™ 6 XAU+ PA6 offers superior heat aging performance in air, which allows this material to perform at higher continuous service temperatures. Due to these characteristics, Ertalon™ 6 XAU+ PA components are often recommended for bearings and other mechanical parts that are subject to wear and that are operating for long periods of time at temperatures over 60°C (140°F).
