PEEK

Main Characteristics

• Extremely high maximum allowable service temperature in air [ 250 ˚C continuously, up to 310˚C for short periods of time]
• High mechanical strength, stiffness and creep resistance, also at elevated temperatures
• Excellent chemical and hydrolysis resistance
• Excellent wear and frictional behavior
• Very good dimensional stability
• Excellent resistance to high energy radiation[gamma-and X-rays]
• lnherent low flammability and very low levels of smoke evolution during combustion
• Good electrical insulating and dielectric properties[except for Ketron HPV PEEK and CA30 PEEK]

Applications

Ketron PEEK is often used to replace PTFE when higher mechanical load bearing capacity, or when superior wear resistance is needed Ketron PEEK is widely selected as a replacement for metal components. Examples of components made for PEEK grades: pump components, valve seats, bearings, rollers, gears, high temperature insulators, components exposed to boiling water or steam.
