PolyEtherEtherKetone (PEEK), a high performance engineering thermoplastic, offers chemical and water resistance similar to PPS (PolyPhenylene Sulfide), but can operate at higher temperatures.
The general purpose grade is unreinforced and offers the highest elongation and toughness of all PEEK grades. The addition of carbon fibers enhances the compressive strength and stiffness of PEEK, and dramatically lowers its expansion rate. This grade offers optimum wear resistance and load carrying capabilities and provides 3-1/2 times higher thermal conductivity than unreinforced PEEK, allowing heat to dissipate from the bearing surface faster. Carbon-filled PEEK is black in color.
Additional formulations (i.e., mineral-filled, bearing, and medical grades) and variants within these grades (FDA compliant, static dissipative, high temperature) are available to meet specific application demands. Contact an Emco Industrial Plastics representative who can help you choose the correct material to meet the needs of your application.
