Solvay KetaSpire® PEEK

Outperforms the Competition

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® AM FILAMENT MS NT1 POLYETHERETHERKETONE (PEEK) 

Ketaspire® PEEK AM Filament MS NT1 provides long-term performance up to 240°C, including exceptional chemical resistance and outstanding wear. These properties make it particularly suited for metal replacement in critical applications in severe end-use environments, such as Oil & Gas, Aerospace and Automotive.

Not All PEEK is Created Equal

Not all commercial PEEK products deliver the same level of performance. KetaSpire® PEEK offers distinct performance advantages due to Solvay’s newer polymer production technology. Depending on the grade, KetaSpire® PEEK offers

• Better fatigue resistance
• 20% higher impact strength
• 60% higher ductility

KetaSpire® Product Line

Solvay’s 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)

Comparison of neat and modified grades

Glass fiber and carbon fiber reinforced KetaSpire® PEEK grades deliver the greater mechanical robustness required for demanding structural applications.

Wear Resistance

Wear properties are enhanced by adding carbon fiber and polymeric lubricants such as PTFE. Torlon® PAI offers the best high-temperature wear resistance.
