What is Ketron™ Sterra™ HPV PEEK used for?
Ketron™ Sterra™ HPV PEEK is commonly used for bearings, bushings, seals, valves, and insulators where low friction, wear resistance, and long service life are required.

Recycled Polyetheretherketone
Ketron™ Sterra™ HPV PEEK is a carbon fibre-reinforced PEEK grade from Mitsubishi Chemical Group, containing graphite and PTFE lubricants for exceptionally low friction, excellent wear resistance, and outstanding machinability. Ideal for high-speed, high-load applications, it is commonly used for bearings, bushings, seals, valves, and insulators.

Unlike standard PEEK, Ketron™ Sterra™ HPV PEEK contains carbon fibre, graphite, and PTFE lubricants, giving it lower friction, improved wear performance, and better suitability for sliding applications.
Yes. Like other PEEK materials, Ketron™ Sterra™ HPV PEEK offers excellent thermal stability and can maintain its mechanical properties in demanding high-temperature applications.
Low-friction PEEK reduces wear between moving parts, improves efficiency, minimises maintenance requirements, and helps extend the lifespan of bearings and other wear components.
