Description
These premium moulded natural hollow billets are manufactured from high‑performance PEEK engineering plastic, offering outstanding mechanical strength, dimensional stability and chemical resistance. Designed as a semi-finished product, they provide a reliable starting point for precision‑machined parts where performance and consistency are critical.
Combining excellent flame retardance with low creep and superb dimensional control, these hollow billets are ideal for demanding applications in aerospace, automotive, electrical and industrial environments. Available in a choice of outside diameters, wall thicknesses and a standard 80 mm length, they allow efficient, low‑waste machining of rings, bushes, insulators and structural components.

- Outside diameters available in 260 mm, 300 mm, 330 mm, 350 mm and 400 mm for a wide range of component sizes.
- Choice of wall thicknesses including 20 mm, 25 mm, 30 mm and 40 mm to suit strength and weight requirements.
- Standard billet length of 80 mm for convenient handling and efficient machining into finished parts.
- Excellent dimensional stability, enabling tight tolerances and consistent part geometry after machining.
- Inherent flame retardant characteristics of PEEK suitable for use in environments with strict fire performance demands.
- Natural, unfilled grade supports predictable machining behaviour and consistent material response.
Key Features and Benefits
- High mechanical strength: Supports demanding load‑bearing and structural applications while maintaining integrity over time.
- Outstanding dimensional stability: Minimises distortion during and after machining, helping to achieve precise, repeatable components.
- Flame retardant performance: Inherent resistance to ignition and flame spread makes the material suitable for safety‑critical systems.
- Chemical and wear resistance: Withstands exposure to many industrial chemicals and offers good wear properties for long service life in harsh environments.
- Efficient material utilisation: Hollow format reduces machining time and waste compared with solid bar when producing rings, bushes and similar parts.
- Versatile sizing options: Multiple diameters and wall thicknesses give design flexibility and allow optimisation for strength, weight and cost.

Frequently Asked Questions
Can these PEEK hollow billets be machined using standard workshop equipment?
Yes, the billets can be machined using conventional metalworking equipment with appropriate tooling and cutting conditions for engineering plastics. Sharp tools, moderate cutting speeds and adequate support are recommended to achieve the best surface finish and maintain tight tolerances.
Are these billets suitable for use in high‑temperature environments?
PEEK offers excellent high‑temperature performance compared with many other engineering plastics, maintaining mechanical strength and dimensional stability at elevated temperatures. The specific service temperature limit will depend on the application, loading and exposure time, so these factors should be considered during design.
How do I choose the most appropriate diameter and wall thickness for my application?
Select an outside diameter that comfortably covers the maximum finished part size, allowing for machining allowances, then choose the closest wall thickness that provides the required strength without excessive weight or waste. For guidance on complex or highly loaded parts, consult your design calculations or seek engineering advice.
