Frequently Asked Questions About Ultem PEI Rods

Q: Can you cut Ultem rods to a custom length?
Yes, we offer CNC cutting and length customization based on your request. Just send us the specs.

Q: What’s the difference between amber and black PEI?
Amber is the natural color of virgin PEI (Ultem 1000). Black versions are often pigmented and may have slightly different thermal or UV properties depending on application needs.

Q: Is Ultem PEI suitable for food-grade or medical-grade use?
Amber Ultem (unfilled) may be compliant with certain FDA or USP Class VI requirements. Contact us for datasheets to confirm compatibility for your specific use case.

Q: What’s the MOQ for bulk or OEM machining orders?
We support low-volume prototype runs and large-scale production. No MOQ for stock items; custom project MOQ depends on complexity—contact us for details.
