Polyether ether ketone (PEEK)
Polyether ether ketone (PEEK) is an engineering thermoplastic resistant to high temperatures, with its melting point at 335 °C (635 °F). Up until 280°C (540°F), PEEK is resistant against hydrolysis and almost every organic or inorganic chemical. PEEK can be formed by injection molding in its liquid state or via extrusion.
With a surface energy of 46mN/m, PEEK has a relatively low surface energy. Therefore, a plasma treatment is carried out before bonding in order to increase this and to strengthen the adhesion.
- Automotive and aerospace industry
- High voltage industry (as an insulating material)
- Medical technology (as it can be sterilized repeatedly and is biocompatible as well as x-ray transparent)
- In dental compound materials as a matrix
- In pharmaceutics and food technology (in production facilities for components with product contact)
- Flexible film circuit carriers in electronics
- Vacuum technology, for very low outgassing rates
