ThermaX PEEK 3D Filament

ThermaX PEEK (PolyEtherEtherKetone) is one of the world’s highest performing polymers. In fact, it is one of the highest performing plastics ever invented. PEEK has exceptional mechanical, thermal and chemical resistance properties that make it a go-to material in some of the most demanding applications where failure is not an option.

The advantages of PEEK include:

• Intrinsically flame resistant and self-extinguishing
• Long-term hydrolytic stability even above 250°C
• Exceptional resistance to a wide range of chemicals, including automotive fluids, fully halogenated hydrocarbons, alcohols and aqueous solutions
• Low emissions of smoke and toxic gases
• Excellent dimensional stability with low thermal deformation, low and uniform thermal expansion coefficient, giving PEEK highly reproducible part-to-part dimensions
• High thermal properties with Tg of 143°C, CUT of 240-260°C and Tm of 343°

Typical applications of PEEK include:

• Seals, gears, bushings, bearings, components for pumps and compressors
• Industries served: automotive, aerospace, defense, semiconductor, oil and gas

Recommended print settings:

• Extruder: 375-410°C
• Bed temperature: 130-145°C
• Bed preparation: nanopolymer adhesive
• Heated chamber: Recommended, a case helps reduce warping and improves print success. 70-140°C if possible
• Holders: The ThermaX™ HTS High Temperature Holder is designed to work with complex, high temperature materials just like this
• Drying instructions: 120°C for 4 hours
