Quick Summary

Polyetheretherketone (PEEK) is a high-strength, radiation-resistant engineering plastic that combines both ether and ketone groups in its molecular structure. It is known for its thermal stability and resistance to chemicals.1

PEEK finds its primary uses in demanding applications such as machine parts, components for nuclear power plants and aerospace, cable insulation, and pump parts. Its robust properties make it suitable for environments where other materials might degrade.1
