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.

Grades

● Ketron® 1000 PEEK
● Ketron® HPV PEEK
● Ketron® GF30 PEEK
● Zeniva® PEEK

● Ketron® LSG PEEK

  • 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 150 °C (the glass transition temperature), the mechanical properties of all Ketron® PEEK grades decrease significantly, and the coefficient of linear thermal expansion increases substantially. For close-tolerance parts operating under high loads at temperatures above 150 °C, Duratron® PAI may be a more suitable choice.
  • Like most reinforced materials, Ketron® GF30 PEEK, HPV PEEK, CA30 PEEK, and TX PEEK exhibit moderate toughness and impact strength. To maximize part durability, all internal corners should be radiused (R > 1 mm) and edges 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.
