As a backbone of high-performance engineering, selecting the right polymer can define a project’s success. Our inventory supports a full range of possibilities, starting with the unfilled PEEK rod known for its excellent chemical resistance and thermal stability. For applications demanding greater mechanical strength, we offer reinforced variants such as Glass Fiber Filled PEEK Rods and Glass fiber reinforced PEEK rod, which deliver enhanced stiffness and improved creep resistance. When ultimate rigidity and low weight are non-negotiable, the Carbon fiber reinforced PEEK rod stands out, and our carbon fiber filled PEEK rods push those properties even further, offering exceptional wear characteristics and dimensional stability under heavy loads. This specialized compound reduces thermal expansion significantly, making it ideal for precision seals, bearings, and structural components in aerospace and medical equipment.
Carbon Fiber Filled PEEK Rods are manufactured using a proprietary blend of polyetheretherketone resin and milled carbon fiber reinforcement, typically at a loading of 30%. This results in a material that exhibits dramatically higher flexural modulus and compressive strength compared to unfilled grades. Below, you will find the detailed product parameters and technical specifications that define these rods.

Available diameter range: 1/4" to 6" (6.35 mm to 152.4 mm). Custom lengths and tight tolerance machining are available upon request. These rods are extruded and stress-relieved to ensure consistent performance across every batch. The black surface finish is conductive, which helps dissipate static charges in sensitive assemblies. In dynamic applications, the reduced friction and self-lubricating nature of Carbon Fiber Filled PEEK Rods extend service life and lower maintenance costs. Typical applications include semiconductor wafer handling, oil and gas downhole tools, high-load bushings, and pump wear rings. All products are traceable to lot and come with full certification, meeting the rigorous standards of ISO 9001 to give engineers confidence in every component.
