Peek, lighten your structures with a high performance material
DEMGY Normandie DEMGY Lemgo DEMGY Euskirchen DEMGY Făgăraș DEMGY PacificPEEK (polyetheretherketone) offers a very high resistance to extreme conditions (high temperature, radiation, chemical resistance, deformation, wear ...). They are a suitable substitute for metal, with the goal of reducing weight. They find applications including medical, automotive, aeronautics, space, semiconductors, electronics and other demanding industries.
The key assets of PEEK
It combines unique thermal properties with mechanical properties and chemical resistance. It can withstand a constant working temperature of 250 ° C and has excellent long-term chemical resistance.
- Low smoke and gas emissions
- Low moisture absorption
- Low coefficient of friction
- Very good electrical characteristics
- Operating temperature from -40 ° C to + 250 ° C (for short periods up to + 310 ° C)
It is also approved by the FDA (Food and Drug Administration is the US Food and Drug 
Administration)
What are the raw versions of the PEEK?
- PEEK hoses
- PEEK sleeves
- PEEK rings
- PEEK rods
- PEEK tubes
- PEEK films
- PEEK plates
- PEEK fibers
