FibreX™ PEEK+GF20 Glass Fiber Reinforced PEEK 3D Printer Filament

FibreX™ PEEK+GF20 (PolyEtherEtherKetone) is one of the highest-performance polymers in world. In fact, it’s one of the highest-performance plastics ever invented. Now reinforced 20% with glass fibers, PEEK+GF20 has exceptional mechanical, thermal, and chemical resistance properties along with its low warp, increased stiffness, and improved dimensional stability. PEEK+G20 is a go-to material in some of the most demanding applications where failure is not an option.

Benefits of PEEK+GF20 Include:

  • Inherently flame resistant and self-extinguishing

  • Long-term hydrolytic stability even above 250°C

  • Outstanding resistance to a broad range of chemicals, including automotive fluids, fully halogenated hydrocarbons, alcohols, and aqueous solutions

  • Low smoke and toxic gas emissions

  • Excellent dimensional stability with low heat creep, low and uniform coefficient of thermal expansion, giving PEEK highly reproducible part-to-part dimensions

  • High thermal properties with a Tg of 143°C, CUT of 260°C, and Tm of 343
