Plate PEEK PEEK® series

rodself-extinguishing

Polyetheretherketone can be used at very high temperatures (about +260 °C) and it shows an extraordinary mechanical strength, toughness, hardness, flexural strength, 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 (even ultraviolet rays only lead to a slight yellow discolouration). PEEK is self-extinguishing properties according to UL 94. PROPERTIES GEHR PEEK® 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
