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 FibreX PEEK+GF20 :
- Inherently flame resistant and self-extinguishing
- Long-term hydrolytic stability even above 250C
- 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 143C, CUT of 260C, and Tm of 343

Abrasive Material
This material is particularly abrasive among 3D printing filaments. Users may find standard brass nozzles are chewed through very quickly compared to standard wear and tear. When worn through, the nozzle diameter will widen inconsistently and the printer will experience extrusion issues.
Because of this, it's strongly recommended this material be printed through a hardened steel nozzle rather than a softer metal. Hardened steel nozzles can often be inexpensive and easily installed depending on your printer manufacturer's instructions.
