Description
This premium medical grade PEEK natural rod is a high-performance engineering plastic designed for demanding medical applications where strength, sterilisation resistance and biocompatibility are critical. Manufactured from high purity polyether ether ketone, it offers outstanding mechanical and thermal properties in a clean, natural, unfilled finish.
Available in a range of diameters and lengths, this PEEK rod is ideal for machining precision medical components, fixtures and supports. Its exceptional rigidity, toughness and thermal stability make it a reliable choice for applications subjected to repeated sterilisation cycles, elevated temperatures and long-term mechanical loading.
Product Features
- Supplied in natural, unpigmented medical grade PEEK for high purity and traceability.
- Available diameters: 16 mm, 20 mm, 32 mm, 36 mm, 50 mm and 60 mm to suit a wide range of machined parts.
- Standard lengths of 1000 mm, 2000 mm and 3000 mm to optimise material yield and reduce waste.
- High rigidity and toughness, offering excellent resistance to impact and mechanical fatigue.
- Outstanding thermal stability, maintaining properties at continuous service temperatures up to approximately 250°C.
- Excellent chemical resistance to common disinfectants and cleaning agents used in medical environments.

Frequently Asked Questions
Can this medical grade PEEK rod withstand repeated autoclave sterilisation?
Yes, PEEK is well known for its excellent thermal stability and can typically withstand repeated steam autoclave cycles without significant loss of mechanical properties, provided it is used within recommended temperature and pressure limits.
What machining practices are recommended for working with this PEEK rod?
The rod can be machined using standard metalworking tools and carbide-tipped cutters. Sharp tools, moderate cutting speeds, adequate support and effective chip removal are recommended to achieve good surface finishes and maintain tight tolerances.
Is this PEEK rod suitable for direct implantable use?
While the material is medical grade, suitability for direct implantation depends on specific regulatory and application requirements. It is the responsibility of the user to verify compliance, conduct appropriate testing and obtain any necessary approvals for implantable applications.
