PEEK FAQs

  • Is PEEK machinable?

    Yes, PEEK (polyetheretherketone) can be machined to a variety of surface finishes. In high-stress/high-temperature applications, PEEK is a great lightweight substitute for most soft metals. It’s resistant to moisture, wear, and chemicals.

  • Can PEEK be 3D printed?

    PEEK can be 3D printed. Its unique properties allow for the creation of almost any complex geometry, some of which cannot be manufactured using other technologies. The slower the 3D printing speed, the more accurate the end result.

  • What is the melting point of PEEK?

    PEEK has a melting point around 341°C (646°F). It has the ability to maintain stiffness and can be used continuously in temperatures up to 260°C (480°F). It can also be used in hot water or steam without compromising physical properties.

  • What is PEEK plastic used for?

    PEEK is often used in the following industries: aircraft, automotive, medical, chemical, semiconductor and microwave to manufacture items used in demanding environments, including pumps, bearings, HPLC columns, compressor plate valves, cable insulation, and piston parts.
