GEHR PEEK-30CF® by GEHR is a polyetheretherketone (PEEK) grade, reinforced with 30% carbon fiber. Exhibits very high mechanical strength, bondability, rigidity even at low temperature, thermal stability, creep resistance and dimensional stability. Offers very high hydrolysis resistance, low resistance to acetone, low notch impact strength, excellent chemical resistance and dielectric properties. Provides toughness, hardness, flexural strength, torsional strength, limited UV stabilization, very high radiation resistance and high temperature resistance (upto 260°C). GEHR PEEK-30CF® is used in bearing shells, piston rings, valve seats, gears, seals, aviation, cog-wheels, pump vanes, fittings, plug connectors for chromatography, wafer carriers and semiconductor industry. Complies with FDA and UL 94 V-0 flame rating.
