KETRON® (PEEK)
Ketron PEEK grades offer chemical and hydrolysis resistance similar to PPS but can operate at higher temperatures. Unreinforced, extruded Ketron PEEK offers good wear resistance and can be used continuously to 480°F (250°C). It can also be used in hot water or steam without permanent loss in physical properties. For hostile environments, PEEK is a high-strength alternative to fluoropolymers. PEEK carries a V-O flammability rating and exhibits very low smoke and toxic gas emission when exposed to flame. Structural & Chemical Integrity to 480°F (250°C)

30% Glass-Reinforced Ketron PEEK
The addition of glass fibers significantly reduces the expansion rate and increases the flexural modulus of PEEK. This grade is ideal for structural applications that require improved strength, stiffness or stability, especially at temperatures above 300°F (150°C).
30% Carbon fiber-reinforced Ketron PEEK
The addition of carbon fibers enhances the compressive strength and stiffness of PEEK, and dramatically lowers its expansion rate. It offers designers optimum wear resistance and load carrying capability in a PEEK-based product. This grade provides 3½ times higher thermal conductivity than unreinforced PEEK-dissipating heat from the bearing surface faster.
Proven Applications
- Pump wear rings 30% - Carbon fiber-reinforced Ketron PEEK improves centrifugal pump efficiency by permitting closer running tolerances and eliminating corrosion, galling and wear problems. (Prior material: Bronze)
- Electrical housing - Ketron PEEK offers precise machinability, mechanical stability and superior electrical insulating characteristics in this coil former that focuses an electron beam to create detail on silicon chips. (Prior material: Epoxy thermoset)
- Bushings, bearings, seals, back-up rings - In applications ranging from aircraft to oilfield drilling, components machined from Ketron PEEK improve performance and reliability. (Prior materials: Reinforced PTFE, PPS, Bronze)
