Free Access to 80,000 Datasheets

Overview of Polyetherketone (PEK) including background, history, advantages, limitations and typical applications.

Background: Polyaryletherketone (PEK) was first prepared in the early 1970s, but the initial process and results were limited in several ways. In 1977 further development by ICI involving polyetherification reactions were eventually successful in creating the first commercial version of polyetheretherketone (PEEK).
