Ketron® Sterra™ HPV PEEK

Recycled poly-ether-ether-ketone

Ketron® Sterra™ HPV shapes are carbon fiber reinforced, with graphite and PTFE lubricants, giving them the lowest coefficient of friction and the best machinability of all PEEK materials. Due to Ketron® Sterra™ HPV PEEK’s combination of low wear, low friction, and high limiting pressure velocity, this PEEK material is often chosen as a solution for high speed service bearings, bushings, insulators, valves, and seals.

As part of the Sterra™ product portfolio, Ketron® Sterra™ HPV contains recycled content and therefore is associated with a significantly lower carbon footprint compared to similar materials derived from non-recycled feedstocks.
