PEEK

Chemical Engineering

PEEK, polyether ether ketone, is a beige semicrystalline thermoplastic that keeps its mechanical strength and chemical resistance at high temperatures and resists thermal degradation and biodegradation. Imperial Chemical Industries invented it in November 1978 and brought it to market in the early 1980s; its PEEK division was later spun out through a management buyout into Victrex PLC. It is machined into bearings, pistons and pumps, used for aerospace and automotive components, chosen for spinal-fusion and other medical implants because it is biocompatible and radiolucent on X-rays, and increasingly printed as a high-performance 3D-printing filament.
