POLYETHERETHERKETONE (PEEK)

KETRON® PEEK

The KETRON PEEK family of materials is based on polyetheretherketone resin. This semi-crystalline advanced material exhibits a unique combination of high mechanical properties, temperature resistance and excellent chemical resistance making it the most popular advanced plastics material.

Main characteristics

• Very high maximum allowable service temperature in air (250°C continuously going up to 310°C for short periods of time)
• High mechanical strength, stiffness and hardness, also at elevated temperatures
• Excellent chemical and hydrolysis resistance
• Excellent wear & frictional behaviour (particularly KETRON PEEK-HPV and PEEK-CA 30
• Very good dimensional stability
• Excellent resistance to high energy radiation (gamma- and X-rays)
• Inherent low flammability and very low levels of smoke evolution during combustion
• Good electrical insulating and dielectric properties (except for KETRON-HPV and PEEK-CA30)

Applications

Scraper blades in heat exchangers, sleeve bearings for steel wire guide rollers, gas analyser structural body parts, pump wear rings.

KETRON PEEK-1000 natural (brownish grey) / black (PEEK)

KETRON PEEK-1000 stock shapes are produced from virgin polyetheretherketone resin and offer the highest toughness and impact strength of all KETRON PEEK grades. Both KETRON PEEK-1000 natural and black can be sterilised by all conventional sterilisation methods (steam, dry heat, ethylene oxide and gamma irradiation). Additionally, the raw material used for the production of KETRON PEEK-1000 natural stock shapes received the Japanese MITI approval which includes testing with respect to solvent extractables and mutagenicity, and its composition 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 make this grade very popular in medical, pharmaceutical and food processing industries.

KETRON PEEK-HPV (black) (PEEK+CF+PTFE+graphite)

The addition of PTFE, graphite and carbon fibres results in a KETRON PEEK "Bearing Grade". Its excellent tribological properties (low friction, long wear, high PV-limits) make this grade the ideal material for wear & friction applications.

Delivery Programme: rod 6 - 100 mm, plate 5 - 60 mm, tube 50 - 200 mm

KETRON PEEK-GF30 natural (brownish grey) (PEEK-GF30)

This 30% glass fibre reinforced grade offers a higher stiffness and creep resistance than KETRON PEEK-1000 and has a much better dimensional stability. This grade is ideal for structural applications supporting high static loads for long periods of time at elevated temperatures. The suitability of KETRON PEEK-GF30 for sliding parts, however, is to be carefully examined since the glass fibres tend to abrade the mating surface.

KETRON PEEK-CA30 (black) (PEEK-CF30)

This 30% carbon fibre reinforced grade combines even better mechanical properties (higher E-modulus, 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 unreinforced PEEK - dissipating heat from the bearing surface faster.

Delivery Programme: rod 6 - 80 mm, plate 5 - 60 mm, tube 50 - 200 mm
