PEEK Monofilament
Product Overview
PEEK (Polyether Ether Ketone) monofilament is a high-performance engineering fiber made from PEEK resin through melt spinning. It features excellent high temperature resistance, outstanding chemical stability, superior mechanical properties, low friction, wear resistance and good biocompatibility. PEEK monofilament is widely used in filtration, industrial conveying, seals, cables, aerospace, automotive, medical devices and other demanding applications.
