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.
