14 Advantages of PEEK

PEEK (polyetherketone) high performance polymer films offer a unique combination of properties including high temperature performance, chemical, hydrolysis and wear resistance, electrical performance and mechanical properties. The composition and inherent purity of the polymers result in low ionic extractables, low outgassing, and extremely low smoke and toxic gas emissions. They are very stable and do not require flame retardant additives to achieve V0 ratings. PEEK films are FDA compliant.

Characteristically, PEEK films can be summarized by the following 14 advantageous properties:

  • very high continuous temperature resistance (260 °C)
  • excellent sliding properties
  • electrically insulating
  • sterilizable
  • resistant to numerous chemicals
  • flame retardant and self-extinguishing
  • very high creep and wear resistance
  • resistant to high-energy radiation
  • resistant to hydrolysis and superheated steam
  • high toughness even at low temperatures
  • low outgassing in vacuum
  • thermoformable
  • good punchability
  • good coating properties

Applications for PEEK films

  • Medical technology
  • Battery production
  • Fuel cells
  • Electronics

PEEK films are now used worldwide in industries such as aerospace, automotive, oil and gas, fiber optics, alternative energy, and medical. This film is considered one of the highest performing materials.

The aryl and ketone components of PEEK support its thermal stability both when processed in the melt and as finished parts. The electrical industry prefers PEEK because of these same properties, which result in high dielectric strength and insulating ability.

Aside from its ability to withstand harsh industrial chemical environments, PEEK’s chemical resistance also means that it does not react when used in the body. In addition, PEEK exhibits many mechanical properties similar to bone. A final advantage of PEEK is that its robust mechanical properties and machinability allow it to replace heavier metal parts in many applications where weight savings are critical. In its relatively short commercial life, PEEK has proven to be an incredibly valuable material that can be used in both the harshest and most sensitive environments.
