PEEK plastic gearrack products: The high-temperature plastic with outstandingmechanical properties. PEEK is a semi-crystalline, highperformance thermoplastic for very demandingapplications.
The maincharacteristics of PEEK are:
- High thermal mechanical bearingstrength
- Creep resistant
- Very tough
- Good chemicalresistance
- Hydrolysis resistant, evenagainst super heated steam
- Good slidingproperties
- Wear resistant
- Electricallyinsulating
- Good machinability
- High resistance to gammaradiation
The preferredfields for the use of PEEK are; mechanical and automotiveengineering, nuclear and vacuum technology, transport and conveyortechnology, textile, packaging and paper processing machinery,electronic and precision engineering, food processing and medicaltechnology, chemical industry, aircraft and aerospaceindustries.
Popular applicationsfor this product are:
Gears, Wear strips, Bushes, Metering pumps, Light mountings, Friction bearings, Ball valve seals, Pump housings, Wafer supports, Plug parts.
