This success rests on a range of highly successful engineering materials and our wealth of experience in this sector, which enables us to always select the right material for your application.


PEEK is distinguished by the sum total of its unusual properties. The following ones are especially important for automotive applications:

  • high mechanical strength combined with high impact strength

  • resistance to high and low temperatures

  • Good abrasion resistance and a low coefficient of friction

  • excellent chemical resistance

  • low moisture absorption combined with very low thermal expansion

  • Freedom from corrosion and weight reduction


PEEK is easy to process, for example, by

injection molding

, the predominant process in automotive construction. But the material is also very easy to extrude and is suitable for



PEEK can be machined, welded, marked, and bonded with ease. This makes it highly suitable for applications in running gears, brakes, steering, engine management, clutches, gears, electronics, sensor technology, and climate management.
