General Description:  

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. It also has very good resistance to wear, dynamic fatigue and radiation. The addition of a mineral filler improves the dimensional stability of PEEK, noted by it's lower coefficient of thermal expansion compared to unfilled PEEK.

Applications include electrical insulation, flexible printed circuit substrates, high temperature labels, flexible surface heaters, pressure sensor membranes, acoustic speaker diaphragms, as well as items used in aerospace and radiation environments.
