PEEK  (PolyEtherEther Ketone)

PEEK Components (PolyEtherEther Ketone)

PEEK (Polyether ether ketone) - is a semicrystalline thermoplastic with excellent mechanical and chemical resistance properties that are retained to high temperatures. PEEK has a glass transition temperature at around 143 °C and melts around 343 °C. It is highly resistant to thermal degradation as well as attack by both organic and aqueous environments. It dissolves completely in concentrated sulphuric acid at room temperature.

Because of its robustness, PEEK is used to fabricate items used in demanding applications, including bearings, piston parts, pumps, HPLC columns, compressor plate valves, and cable insulation. It is one of the few plastics compatible with ultra-high vacuum applications. PEEK is considered an advanced biomaterial used in medical implants. It is extensively used in the aerospace, automotive and chemical process industries.


Typical applications
