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.


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

Packed with your favorite products, detailed information, and essential technical data. Whether your brand new to 3-D printing or need to find a specific filament that best fits your project, our catalog has everything you need in one easy-to-navigate place!

Explore key attributes like tensile strength, flexural strength, glass transition, and fire testing performance. Whether you're prototyping, creating functional parts, or printing detailed models, these property graphs will help you find the perfect filament for your project.
