'''Polyether ether ketone''' ('''PEEK''') is a colourless [[organic compound|organic]] [[thermoplastic]] [[polymer]] in the [[polyaryletherketone]] (PAEK) family, used in engineering applications. The polymer was first developed in November 1978,<ref>{{Cite web|title=Victrex celebrates 40 years of PEEK success|url=https://www.victrex.com/en/news/2018/11/40-years-of-peek-success|access-date=2021-11-01|website=Victrex|language=en}}</ref> later being introduced to the market by Victrex PLC, then [[Imperial Chemical Industries]] (ICI) in the early 1980s.<ref>{{cite web|url=http://drakeplastics.com/peek/|title=Why PEEK?|website=drakeplastics.com|access-date=23 April 2018}}</ref>
