Polyetheretherketone (PEEK)
usd/kg
Polyetheretherketone (PEEK) offers high-temperature resistance, wear resistance, corrosion resistance, and self-lubricating properties. It also has superior insulation and chemical resistance compared to metal alloys. With a density about half that of aluminium alloy, PEEK enables lightweight construction while maintaining high strength and rigidity.
PEEK is around 30% crystalline and usually sits alongside materials such as polyoxymethylene (POM), acetal, and Polyamide (PA66), nylon, as higher strength semi-crystalline thermoplastic polymers. PEEK can be used in place of POM or
PA66 where higher strength, stiffness or temperature resistance is required. The strength and stiffness of PEEK are
being used in applications where the resistance required would typically require the properties of metals.
Only four companies worldwide – Victrex (UK), Solvay (Belgium), Evonik (Germany), and China’s Zhongyan Polymer Materials – produce PEEK at large scale. Trade names include Victrex (Victrex), Ketaspire (Syensqo, formerly Solvay), Vestakeep (Evonik), Tecapeek (Ensinger), Ketron (Mitsubishi), Sustapeek (Röchling) and Zeniva (Solvay).

PEEK-CF30 is used for demanding applications where a high-performance engineering plastic is required to deliver exceptional strength, wear resistance, and thermal stability, particularly in environments too severe for standard polymers or metals.
