Ketron® CA30 Polyetheretherketone PEEK is a 30% carbon fiber-reinforced grade that exhibits even higher stiffness, mechanical strength, and creep and wear resistance that Ketron® GF30 PEEK. With a significantly reduced thermal expansion, optimum load carrying capabilities, and high thermal conductivity rates, Ketron® CA30 PEEK components are often favored for their ability to extend part life and rapidly dissipate heat in bearing applications.
