Material Notes:
Polyether etherketone can be used at very high temperatures and it shows good mechanical strength, toughness, hardness, flexural strength, and torsional strength. PEEK exhibits excellent chemical resistance, very good dielectric properties up to 260°C and a very good resistance to all kinds of radiation.Properties:very high mechanical strengthvery high rigidityvery high thermal stabilityvery high creep resistancevery high dimensional stabilityvery high radiation resistancevery high hydrolysis resistancerelatively low notch impact-strengthlow resistance against acetoneApplications include bearing shells, piston rings, valve seats, gears, seals, aviation, cog-wheels, pump vanes, fittings, plug connectors, and wafer carriers.
