Outperforms the Competition
KetaSpire® PEEK (polyetheretherketone) offers the best combination of fatigue resistance and chemical resistance. PEEK chemical resistance is similar to that of PPS (polyphenylene sulfide). However, PEEK can operate at higher temperatures and retains its excellent mechanical properties at continuous-use temperatures up to 240 °C (464 °F), allowing it to replace metal in severe end-use environments. Glass fiber-reinforced and carbon-fiber-reinforced grades, as well as specialty grades, provide a wide range of performance options.
Why KetaSpire® PEEK?
- Exceptional chemical resistance to organics, acids and bases
- Very good wear and abrasion resistance
- Best-in class fatigue resistance
- Excellent dimensional stability
- Excellent resistance to hydrolysis in boiling water and superheated steam
- Superior dielectric with low loss at high temperatures and frequencies
- Ease of processing
- High purity
KetaSpire® PEEK is produced to the highest industry standards and is characterized by a distinct combination of properties, which include excellent wear resistance, best-in-class fatigue resistance, ease of melt processing, high purity, and excellent chemical resistance to organics, acids, and bases.
These properties make it well-suited for applications in many areas, including additive manufacturing, aerospace, automotive, healthcare, oil & gas, and semicon.
KetaSpire® PEEK XT delivers the chemical resistance and ease of processing of standard PEEK along with improved mechanical and electrical properties. Compared to standard PEEK, it has a 20 °C (36 °F) higher glass transition temperature and a 45 °C (81 °F) higher melting temperature.
While other high-temperature polyketones like PEK, PEKK and PEKEKK exhibit thermal properties comparable to KetaSpire® PEEK XT, they lack the chemical resistance of both standard PEEK and KetaSpire® PEEK XT.
