Polyetheretherketone (PEEK)

Polyetheretherketone (PEEK)

Description

PEEK is a semi-crystalline thermoplastic with excellent sliding properties, very good mechanical properties, even under thermal load and an excellent resistance to chemicals.

The PEEK semi-finished products that we offer come in sheets, rods and tubes form, from these we can also manufacture finished parts made to specific requirements.

Application

Applications:

  • Gear wheels
  • Friction bearings,bobbins
  • Fitting or hot water meters
  • Valves
  • Piston rings
  • Parts for car engines like bearing cages etc etc

Main Properties

The main properties of PEEK are:-

  1. High continuous working temperature (+250 C in air)
  2. High mechanical strength.
  3. High rigidity.
  4. High creep resistance, also at high temperatures.
  5. Good sliding properties.
  6. High wear resistance.
  7. High dimensional stability.
  8. Excellent chemical resistance.
  9. Resistant to hydrolysis.
  10. Good electrical insulator.
  11. Radiation resistant.
  12. Physiologically safe.
  13. Fire resistant (UL 94 VO).

Color: Natural, black

PEEK ideally combines good sliding properties with high mechanical strength and thermal stability as well as excellent chemical resistance. Because of this, it is suitable for sliding applications. PEEK can be modified with carbon fiber, PTFE and graphite-with highest wear resistance, a low coefficient of friction and high pv limiting value – are available for component parts that are subject to especially high abrasion and wear.
Because of its unique properties, PEEK finds application in the chemical, pharma, food, nuclear, petrochemical, aerospace, and defence technologies.
