The Ketron PEEK family of materials is based on the polyetheretherketone resin.
Ketron Peek is a semi-crystalline advanced material that exhibits a unique combination of high mechanical properties, temperature resistance and excellent chemical resistance making Ketron PEEK the most popular advanced plastics material.
Ketron Peek is available in various grades including PEEK-HPV (bearing grade), PEEK-GF30 (glass fibre reinforced), PEEK-CA30 (Carbon fibre reinforced) and PEEK-TX (internally lubricated).
The initial aim is to increase values for strength and rigidity, especially at high temperatures. The plastic becomes harder and has lower elongation, i.e. it is less elastic and breaks when strained. Improved dimensional stability and tighter tolerances can be achieved. The coefficient of thermal expansion is significantly lower. In some cases there are similarities with aluminium or steel. During machining operations the fibre additives cause increased tool wear.
30% Carbon fibre-reinforced Ketron PEEK improves centrifugal pump efficiency by permitting closer inning tolerances and eliminating corrosion, galling and wear problems (Prior materials: Bronze)
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 materials: Epoxy thermoset)
In applications ranging from aircraft to oilfield drilling, components machined from Ketron PEEK improve performance and reliability. (Prior materials: Reinforced PTFE, PPS, Bronze)
From 150°C onwards (above the glass transition temperature), the mechanical properties of all Ketron Peek grades drops off significantly and the coefficient of linear thermal expansion increases considerably. Consequently, a material like Torlon* PAI would be better suited for close tolerance parts operating under high loads at temperatures over 150°C.
Like most reinforced materials, Ketron Peek-HPV, Ketron Peek GF30, Ketron Peek CA30 and Ketron Peek TX exhibits a moderate toughness and impact strength. Therefore, all "internal" corners of parts made from these materials should be radiused (R> 1mm) and edges chamfered to maximise part toughness.

Ketron PEEK-1000 stock shapes are produced from virgin polyetheretherketone resin and offer the highest toughness and impact strength of all grades. The composition of the raw materials used for the production of the natural stock shapes complies with the directives of the European Union and the American FDA regulations concerning plastic materials intended to come into contact with foodstuffs. These features, added to its excellent sterilisability by means of steam, dry heat, ethylene oxide and gamma irradiation, make this grade very popular in medical, pharmaceutical and food processing industries.
The addition of carbon fibres, PTFE and graphite to virgin PEEK results in a "Bearing Grade". Its excellent tribological properties (low friction, long wear and high Pressure-Velocity capabilities) make this grade especially suited for bearing and wear applications.
This 30% glass fibre reinforced grade offers higher stiffness and creep resistance than Ketron PEEK-1000 and has a much better dimensional stability. Ketron PEEK-GF30 is very appropriate for structural parts carrying high static loads for long periods of time at elevated temperatures. Its suitability for sliding parts, however, is to be carefully examined since the glass fibres tend to abrade the mating surface.
This 30% carbon fibre reinforced grade combines even higher stiffness, mechanical strength and creep resistance than Ketron PEEK-GF30 with an optimum wear resistance. Moreover, the carbon fibres provide 3.5 times higher thermal conductivity than virgin PEEK, dissipating heat from the bearing surface faster.
This new member of the Ketron PEEK family has been developed especially for the food industry. Like Ketron PEEK-1000, this new internally lubricated material has a food contact compliant composition, but offers far superior wear and frictional performance, making it especially suitable for a wide variety of bearing and wear applications in the 100 to 200°C service temperature range.
