PEEK - Polyetheretherketone

Polyetheretherketone (PEEK) is the most common and widely sold member of the polyaryletherketone family (PEAK). PEEK is a semi-crystalline thermoplastic with excellent mechanical and chemical resistance properties that are retained to high temperatures. It is highly resistant to thermal degradation, as well as to attack by both organic and aqueous environments.

PEEK is mainly used in medical & healthcare applications, automotive electrical & electronic, aerospace Applications, Oil & gas, etc.
