Description
These premium high-performance natural rods are manufactured from transparent amber PEI (polyetherimide), a high‑rigidity engineering plastic designed for demanding mechanical and thermal applications. Supplied in a wide range of diameters and lengths, they offer outstanding dimensional stability and consistent machinability for precision components.
Combining exceptional temperature resistance with excellent strength and stiffness, these PEI rods are ideal for replacing metal in weight‑critical designs while maintaining reliable performance. Commonly used in aerospace, automotive, electronics, medical and industrial equipment, they provide a robust solution where conventional plastics may fail.

Frequently Asked Questions
Can these PEI rods be machined using standard workshop equipment?
Yes, the rods can generally be machined using standard metalworking equipment such as lathes and milling machines. Sharp tools, appropriate feeds and speeds, and good workpiece support are recommended to achieve a high‑quality finish and maintain dimensional accuracy.
Are the rods suitable for continuous use at high temperatures?
These rods are made from engineering‑grade PEI, which offers excellent resistance to elevated temperatures and is suitable for continuous high‑temperature service in many applications. Always confirm the specific operating temperature requirements of your application and compare them with typical PEI performance data.
How do I choose the right diameter and length for my project?
Select a rod diameter that comfortably exceeds the largest finished dimension of your machined part, allowing for machining allowances and tolerances. Choose the nearest available length (1000, 1220, 2000, 2440 or 3000 mm) that minimises waste while providing enough material for workholding and any test pieces you may need.
