HPMs – High-performance materials
PEEK PVX
PEEK PVX is a PEEK of suitable quality for bearings. The material contains added carbon, PTFE and graphite, which render it excellent in sliding applications. Therefore, the material is suitable for use as a raw material for bearings in applications subjected to high loads. We deliver PEEK PVX as plastic sheets, rods and hollow rods.
