GEHR Plastics PEEK 450™
Categories:	Polymer; Thermoplastic; Polyketone; Polyetheretherketone (PEEK)
Material Notes:	Polyetheretherketone can be used at very high temperatures (about +500 °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 +500 °F and a very good resistance to all kinds of radiation (even ultraviolet rays only lead to a slight yellow discoloration). PEEK is self-extinguishing properties according to UL 94. Features: Very high mechanical strength; Very high rigidity (also at low temperature); Very high thermal stability; Very high creep resistance; Very high dimensional stability; Very high radiation resistance; Very high hydrolysis resistance; Relatively low notch impact strength; Low resistance to acetone Applications: Bearing shells; Piston rings; Valve seats; Gears; Seals; Aviation; Cog wheels; Pump vanes; Fittings; Plug connectors for the chromatography; Wafer carriers; Semiconductor industry Information provided by GEHR Plastics, Inc.
