General Description : A high performance thermoplastic with the characteristics common to this group - strong, stiff, hard, high temperature resistance, good chemical resistance and inherently low flammability and smoke emission. PEEK is amber in color and usually semi-crystalline and opaque, except thin films are usually amorphous and transparent. It also has very good resistance to wear, dynamic fatigue and radiation, but it is difficult to process and very expensive. Filled grades, including ones designed for bearing-type applications are also available as special order items.
Applications include flexible PCBs (film), fibers and monofilaments, injection moulded engineering components and items used in aerospace and radiation environments.
