PA66 is known for its excellent mechanical, thermal and chemical resistance properties. This material offers a combination of strength, stiffness and toughness making it suitable for applications that require robust, durable and dimensionally precise components. Its low moisture absorption ensures that its mechanical properties remain stable even in humid environments. PA66 exhibits higher tensile, compressive and flexural strength compared to PA6, providing better ability to withstand high loads. It also has good wear resistance and dynamic stress resistance; ideal for applications subjected to repeated mechanical stress. From a thermal standpoint, PA66 has good heat resistance and can operate at relatively high temperatures without significant deformation or loss of mechanical properties.
