KetaSpire PEEK KetaSpire PEEK (polyetheretherketone) offers the best combination of fatigue resistance and chemical resistance, which is similar to PPS (polyphenylene sulfide). However, PEEK can operate at higher temperatures and retains its excellent mechanical properties at continuous-use temperatures up to 240 C (464 F), allowing it to replace metal in severe end-use environments. Glass fiber-reinforced and carbon fiber-reinforced grades provide a wide range of performance options. KetaSpire Product Line Solvays KetaSpire PEEK product line includes: Neat grades (lubricated and non-lubricated) Glass fiber and carbon fiber reinforced grades (low and high melt flow) Wear resistant SL grades (lubricated and non-lubricated) Natural-colored powders (coarse, fine, super-fine and ultra-fine) Packing spec: 25kgs per bag.
