PEI Plastic Machining

A Guide to PEI CNC Machined Parts: Properties, Applications and Design Considerations

What is PEI?

PEI (Polyetherimide) is a high performance amorphous thermoplastic which is typically transparent amber in colour.

PEI plastic is commonly used for structural components requiring high strength and rigidity at elevated temperatures as well as broad chemical resistance.

Please see our PSU (Polysulfone) page for an alternative high performance thermoplastic which has similar characteristics but is cheaper and more readily available.
