PEEK 450FE20 offers the lowest coefficient of friction of all ketone based polymers. It offers unique performance among the bearing grade PEEKs by enabling sealing at lower pressures than 10-10-10 PEEKs like 450FC30 or carbon fiber reinforced grades like 450CA30 while still offering excellent wear resistance. PEEK 450FE20 contains 20% uniformly dispersed PTFE powder making it ideal for intermittent service bushings and rotors in reusable medical devices and analytical instruments. 450FE20 has a 50% lower coefficient of friction and a wear rate that is only 25% that of PEEK NT. PEEK 450FE20 is FDA compliant for direct food contact applications.
