Ketron® Sterra™ CA30 PEEK

Recycled poly-ether-ether-ketone

Ketron® Sterra™ CA30 is a 30% carbon fiber-reinforced PEEK 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® Sterra™ CA30 PEEK components are often favored for their ability to extend part life and rapidly dissipate heat in bearing applications.

As part of the Sterra™ product portfolio, this material contains recycled content and exhibits a significantly lower carbon footprint compared to similar materials derived from non-recycled feedstocks. For details, please refer to the respective environmental data sheet.
