Polyether ether ketone (PEEK) is a colourless organic thermoplastic polymer in the polyaryletherketone (PAEK) family, used in engineering applications. It was invented in November 1978[2] and brought to market in the early 1980s by part of Imperial Chemical Industries (ICI) that later became Victrex PLC.[3]
