Polyetheretherketone [PEEK]

PEEK materials, derived from polyetheretherketone (PEEK) resin, combine outstanding mechanical strength, exceptional temperature resistance, and superior chemical resistance, making them a top choice among advanced plastics.

  • Very high maximum allowable service temperature in air [250 °C continuously, up to 310 °C for short periods of time]
  • High mechanical strength, stiffness and creep resistance, also at elevated temperatures
  • Excellent chemical and hydrolysis resistance
  • Excellent wear and frictional behavior
  • Very good dimensional stability
  • Excellent resistance to high energy radiation [gamma- and X-rays]
  • Inherent low flammability and very low levels of smoke evolution during combustion
  • Good electrical insulating and dielectric properties [except for Ketron™ HPV PEEK and CA30 PEEK]
  • Above the glass transition temperature, approximately 150 °C, the mechanical properties of PEEK grades decrease significantly, while the coefficient of linear thermal expansion increases.
  • Therefore, for parts operating under load at temperatures above 150 °C and requiring tight tolerances, an alternative material such as PAI may be more suitable.Reinforced grades such as GF30 PEEK and HPV PEEK may exhibit moderate toughness and impact resistance.
  • To improve toughness, internal corners should be rounded with a radius greater than 1 mm, and edges should be chamfered.
  • Ketron™ PEEK is an ideal alternative to PTFE when greater load-bearing capacity or enhanced wear resistance is needed.
  • It is also frequently selected to replace metal components in demanding applications such as pump components, valve seats, bearings, rollers, gears, high-temperature insulators, and parts exposed to boiling water or steam.
