PEEK rod is a engineering material that has become an essential resource across a range of industries, valued for its unique blend of mechanical strength, thermal stability, and chemical resistance. Available in rod form, PEEK (polyether ether ketone) offers manufacturers a versatile option for producing precision components that must endure demanding environments. High Performance Polymer provides PEEK rods in a variety of sizes, with lengths of 1000mm and diameters ranging from 4mm to 200mm. These rods are available in both 450G, a general-purpose grade, and GF30, which is reinforced with glass fibres for enhanced stiffness and strength. Additionally, custom 'cut to size' rods are available to suit various applications. If a specific size isn't listed, High Performance Polymer can manufacture PEEK rods to your exact specifications.
The demand for PEEK rods is largely driven by their ability to be machined into high-precision parts that are critical for industries like aerospace, oil and gas, medical, and electronics. In these sectors, materials are often required to endure high temperatures, harsh chemicals, and mechanical stress, making PEEK an ideal choice. For example, in aerospace, PEEK rods are often machined into bushings and bearings that can handle the extreme conditions of flight, including temperature fluctuations and high mechanical loads. Traditional materials like aluminium or nylon may fail under these conditions—aluminium is prone to corrosion and requires protective coatings, while nylon may soften under heat—whereas PEEK remains stable and reliable.
In the medical field, PEEK rods are highly valued for their biocompatibility and ability to withstand sterilisation methods like autoclaving. Medical device manufacturers often use PEEK rods to machine surgical instruments and implantable devices, where the material's non-reactive properties and high strength offer significant advantages over metals like stainless steel or plastics like polypropylene. For instance, in spinal implants, PEEK rods provide the necessary mechanical support while being lightweight and radiolucent, which is beneficial for post-surgical imaging. Metals, in contrast, can interfere with X-rays and MRIs, while cheaper plastics may degrade over time when exposed to bodily fluids or repeated sterilisation cycles.
The oil and gas industry also finds PEEK rods invaluable for their chemical resistance and high-pressure tolerance. Downhole drilling equipment, valve components, and seals are commonly machined from PEEK rods due to their ability to withstand aggressive chemicals, high pressures, and extreme temperatures. Cheaper materials like polyethylene or PVC are often unsuitable for these environments because they are more susceptible to chemical attack and deformation under heat. In contrast, PEEK’s robust properties ensure that components last longer and require less maintenance, providing a cost-effective solution for high-stress applications.
PEEK rods are manufactured through extrusion or compression moulding processes, which result in a homogeneous, high-quality material that can be machined into precise shapes and dimensions. The rod form is particularly desirable because it allows for flexible manufacturing. Engineers can machine the rods into various custom parts like gears, seals, insulators, or structural components with tight tolerances. This adaptability makes PEEK rods a favourite among industries that require highly specialised components capable of withstanding extreme conditions.
In comparison to inferior materials, PEEK rods offer unmatched performance across multiple dimensions. Polymers like polypropylene or polyamide, while more affordable, lack the mechanical strength, heat resistance, and chemical resilience of PEEK. Similarly, metals such as aluminium and stainless steel, although strong, are heavier, prone to corrosion, and often require additional treatment to perform effectively in challenging environments. PEEK offers a lightweight yet durable alternative, providing the strength of metal without the weight and the versatility of plastic without the performance trade-offs.
High Performance Polymer ensures that a range of sizes and grades are available, with PEEK rods in lengths of 1000mm and diameters ranging from 4mm to 200mm. The 450G grade offers a balance of performance and machinability for general applications, while the GF30 grade, reinforced with glass fibres, delivers enhanced strength and stiffness for more demanding conditions. For specialized applications, custom ‘cut to size’ rods are available, and if you don’t see the size you need listed, we can manufacture PEEK rods to your specific requirements, ensuring you get exactly what your project demands.
