PEEK Rods

PEEK (polyether ether ketone) rods are solid cylindrical profiles produced by an extrusion or molding process. These rods are ideal substrates for the manufacture of a wide range of high-performance engineering components using precision machining methods such as turning, milling, drilling, etc. PEEK rods inherit the excellent properties of the PEEK material, including excellent resistance to high temperatures, high mechanical strength and rigidity, excellent chemical resistance, and good dimensional stability. They are widely used in industrial applications where they are subjected to extreme working conditions.

Classifications

Common PEEK rod classifications

To meet the needs of different application environments, PEEK rods are often modified by the addition of different reinforcing materials or lubricants. The main classifications include:

64088326d930d

Unfilled PEEK / Natural PEEK Rod

Made from pure PEEK resin without any fillers. This type of rod exhibits the inherent high toughness, ductility, and excellent electrical insulation properties of PEEK.

30% Glass Fiber Reinforced PEEK Rod

30% (w/w) short-cut glass fibers are uniformly dispersed in the PEEK matrix, enhancing stiffness, tensile strength, creep resistance, and dimensional stability at high temperatures by lowering thermal expansion. While toughness decreases, chemical resistance remains excellent.

30% Carbon Fiber Reinforced PEEK Rod

Contains 30% (w/w) carbon fiber reinforcement. Carbon fibers provide higher stiffness and strength than glass fibers, while giving the material excellent wear resistance and a lower coefficient of thermal expansion. Importantly, the addition of carbon fibers makes the material electrically conductive or antistatic.

Tribological PEEK Rod

Bearing Grade / Tribological PEEK Rod

This PEEK grade is optimized for friction and wear applications, with additives like carbon fiber, graphite, and PTFE for low friction, excellent wear resistance, and high PV performance. Though slightly lower in strength than CF30 PEEK, it excels in sliding and rotating uses.
