PEEK – ThermaX




ThermaX PEEK


ThermaX PEEK (PolyEtherEtherKetone) is one of the highest-performance polymers in world. PEEK has exceptional mechanical, thermal, and chemical resistance properties making it a go-to material in some of the most demanding applications.

Print ThermaX PEEK parts with Funmat HT Enchanced High-Temp 3D Printer.


PEEK is extremely robust, and is used in many very demanding applications where most other materials just won’t do. These include high-stress components in vehicles,  including valves, pistons and bearings; aircraft exterior components and engine parts; routinely used medical tools; and electrical components. PEEK’s high chemical resistance, physical toughness, high heat resistance and long-term durability make the ideal choice for many demanding industrial applications.
