PEEK (Polyetheretherketone) is a unique engineering thermoplastic offering high temperature stability, toughness, rigidity, and creep resistance. It is resistant to a wide range of solvents, making it an excellent material for use in a broad spectrum of applications where thermal, chemical and combustion properties are critical to performance.

The addition of glass or carbon fibers or other reinforcing materials can enhance the mechanical and thermal properties of PEEK, which is produced in both compression-molded and extruded forms, with differentiated properties for each. Molded PEEK components absorb much less water than many other thermoplastics.

Polymershapes offers PEEK in multiple grades and forms, in a variety of sizes. It is available in both natural and black, and several grades that meet FDA, USDA, UL-94 Flame Class, 3-A Dairy and ASTM/Mil-Spec requirements.

Polymershapes can meet your PEEK needs with sheet, rod and tube from leading edge suppliers including Ketron® and Semitron® from Quadrant Engineering Plastics. You can rely on our expert fabrication capabilities to ensure you get just the right amount of material for your projects: We will deliver the sheet, plate, rod or tube you want, in the lengths, widths and thicknesses you need.
