PEEK is used to fabricate items for demanding applications, including [[Bearing (mechanical)|bearings]], [[piston]] parts, [[pumps]], [[high-performance liquid chromatography]] columns, compressor plate [[valves]], and [[electrical cable]] [[Electrical insulation|insulation]]. It is one of the few plastics compatible with [[ultra-high vacuum]] applications, which makes it suitable for aerospace, automotive, and chemical industries.<ref name=":0">{{Cite web|title=PEEK (Polyether Ether Ketone)|url=http://www.scientificspine.com/spinal-materials/peek.html|website=www.scientificspine.com|access-date=2020-05-06}}</ref> PEEK is used in [[medical implant]]s, for example in creating a partial replacement skull in neurosurgical applications.
