Polyetheretherketones

Abstract

Polyetheretherketone (PEEK) was first produced in 1978 in the UK laboratories of Imperial Chemical Industries. The polymer initially was conceived as a high temperature‐resistant, tough cable‐insulation material. However, since commercialization of the polymer in 1981, the combination of ease of processing and excellent thermal stability and mechanical properties at high temperatures established PEEK as a general‐purpose molding and extrusion material in both natural and reinforced forms for high performance applications. KetaSripe and AvaSpire from Solvay and Victrex PEEK from Victrex are the commercial products available. The conventional processability of PEEK has resulted in a wide range of modified products incorporating glass, carbon or particulate fillers. Typical industries using the polymers are electrical, automotive, aerospace, chemical, medical, and engineering plastics to name a few.

Processing and Properties of Bioactive Surface-Porous PEKK

“…The representative PAEKs are poly ether ether ketone (PEEK), poly ether ketone ketone (PEKK), and poly ether ketone ether ketone ketone (PEKEKK) . PAEKs have been successfully applied to a variety of industrial areas including oil and gas, automobile, aerospace, electronics, and healthcare. , PAEKs medical applications include implants for spinal fusion and nonfusion, orthopedic and craniofacial procedures, and instruments or provisionals for dental and cardiovascular applications. Among medical PAEKs, PEEK has received the most attention because of its seminal and wide applications for spinal interbody fusion devices. , Compared to PEEK, PEKK has advantages such as higher thermal stability, better mechanical performance, versatile chemistry due to two ketone bonds, and structural variation between amorphous and semicrystalline phases .…”

Time‐dependent changes of surface properties of polyether ether ketone caused by air plasma treatment

“…The chemical structure of polyaromatic ketones brings about stability at high temperatures (exceeding 300 °C), resistance to chemical and radiation damage, compatibility with many reinforcing agents (such as glass and carbon fibres) and greater strength (on a per mass basis) than many metals, making it highly attractive in industrial applications …”
