PEEK CARBON30
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.
Profile
- Very high max. allowable service temperature in air (250°C continuously going up to 310°C for short periods)
- High mechanical strength, stiffness and hardness, also at elevated temperatures
- Excellent chemical and hydrolysis resistance
- Excellent wear & frictional behaviour (particulary KETRON PEEK-HPV and PEEK-CA30)
- Very good dimensional stability
- Inherent low flammability and very low levels of smoke evolution during combustion
- Good electrical insulating and dielectric properties (except for KETRON PEEK-HPV and KETRON PEEK-CA30)
- Excellent resistance against high energy radiation (gamma and X-rays)
Applications
- Pump wear rings
- KETRON PEEK-CA30 pump wear rings improve centrifugal pump efficiency by permitting closer running tolerances and eliminating corrosion, galling and wear problems.
- Structural parts
- KETRON PEEK is used for vacuum wand handles during semiconductor manufacturing. They typically contact heat and common process chemicals in use.
- Bushings, bearings, seals, back up rings
- In applications ranging from aircraft to oilfield drilling, components machined from KETRON PEEK improve performance and reliability.
- Scraper blades in heat exchangers
- The scraper blades of surface heat exchangers used in food, dairy and chemical industries are made of KETRONŽ PEEK-1000. Its excellent mechanical strength and stiffness at elevated temperatures, high wear resistance and excellent chemical and hydrolysis resistance make it the ideal material for this application.
- Sleeve bearings for steel wire guide rollers
- KETRON PEEK-HPV sleeve bearings for steel wire guide rollers used in caustic baths during the wire drawing process, provide an increased lifetime at a much lower cost than the steel ball bearings used at first. This grade was chosen based on its chemical resistance, excellent wear resistance and high load capacity at elevated temperatures.
- Gas analyser structural body parts
- The three main structural body parts of a gas analyser used by NASA in satellites are made from KETRON PEEK-1000. Providing good chemical resistance, high temperature resistance and excellent resistance to high energy radiation, this grade assures long life and high reliability. Two more reasons for choosing KETRON PEEK-1000 are its excellent machinability and very good dimensional stability.
