PEEK

GEHR PEEK®

Polyetheretherketone can be used at very high temperatures (+480 °F) and it shows an extraordinary mechanical strength, toughness, hardness, flexural strength, torsional strength. PEEK exhibits excellent chemical resistance, very good dielectric properties up to +480 °F and a very good resistance to all kinds of radiation. Importantly it is self-extinguishing according to UL 94. 

Properties:

  • very high mechanical strength
  • very high rigidity
  • very high thermal stability
  • very high dimensional stability
  • very high radiation resistance
  • very high hydrolysis resistance
  • notch impact-strength relatively low
  • low resistance to acetone
  • high wear resistance at higher temperatures

Application:

Bearing shells, piston rings, valve seats, gears, seals, aviation, pump vanes, fittings, plug connectors, wafer carriers, semiconductor industry.

GEHR PEEK-mod®

Reinforced with 10% of each PTFE, graphite and carbonfibre. Very good friction and wear and tear properties.

GEHR PEEK-30GF®
