Excellent thermal properties – Unfilled PEEK offers high strength and excellent resistance to high temperatures, and will not melt until it reaches about 650 degrees Fahrenheit.What is it about PEEK that makes it a natural fit for so many engineering applications? Regardless of the specific chemistry it is the polyketone chemical structure that makes PEEK so formidable in so many environments. This PAEK family covers a number of different compositions with different ratios of ether groups to ketone groups, the most common of which is PEEK. Put simply, it refers to the chemical structure of the polymer although most polymer scientists identify PEEK as being part of the broader family of ketone polymers called polyarylether ketones (PAEKs). PEEK is short for polyether ether ketone, which doesn’t make sense to many other than those with a strong chemistry background. Today Solvay is the only US-based producer of PEEK resin. Name recognition still favors the Victrex brands but others led by Solvay’s Ketaspire PEEK are gaining both volume and market share each year. Others including Solvay entered PEEK resin production in the early 2000s after Victrex PLC’s patent rights expired so today end users and specifiers have no shortage of PEEK resin grades from which to choose. Glass and carbon reinforced grades are among the strongest of all thermoplastics at room temperature and unfilled grades are highly resistant to some of the most chemically aggressive environments including high-pressure steam.įirst introduced by Victrex PLC, then ICI (Imperial Chemical Industries) in the early 1980s it has been gaining use for nearly 40 years. It is known for its impressive durability in punishing environments. PEEK is a workhorse – perhaps the closest to a perfect material that is utilized in a wide range of industries and in a variety of applications.
