In comparison to basic PEEK, glass-filled PEEK has improved mechanical and thermal properties, as well as good resistance to corrosive chemicals and electrical insulation.PEEK in bearing grade offers improved wear and bearing qualities. Glass fiber is a bearing material with extremely high performance and wear-enhancing additives.

Available PEEK grades that comply with FDA regulations.For use in the food and beverage processing and pharmaceutical industries, optical, metal, and X-ray detectable PEEK is a dark blue detectable PEEK that complies with FDA regulations. This metal- and x-ray-detectable material provides exceptional resistance to a wide range of cleaning agents and a heat deflection temperature of over 300°F.

Best practices call for using a filled grade of a stable (low CTE) base polymer when polymers are needed for applications that include significant fluctuations in temperature. PEEK is a promising contender for applications needing plastics with CTEs as close as feasible to those of metals because when fillers are added to highly stable base polymers like PEEK, the resulting composites display extremely low CTE values.

PEEK (polyetheretherketone) is a high-performance engineering plastic with outstanding resistance to harsh chemicals, excellent mechanical strength, and dimensional stability. It also offers hydrolysis resistance to steam, water, and sea water. PEEK is suitable for continuous use at temperatures up to 338oF (170oC) and has a proven track record in demanding environments like aerospace.
