Ultem 1000 PEI, amber
Polyetherimide
Amber, flame-retardant polyetherimide with inherent strength and clarity.
Ultem 1000 is an amber, transparent-in-thin-section polyetherimide known for its combination of strength, heat resistance, and inherent flame retardance without additives. It's a mainstay in aerospace interiors and electrical applications where flammability ratings matter.

Handling notice
- Ultem 1000 PEI, amber carries residual stress from how the plate was made. Cutting it free lets that stress release, and a 12x12 blank can bow 0.010-0.025 in within 48 hours. Stress-relief annealing is available at quote time.
- Ultem 1000 PEI, amber is stress-crack sensitive; our cleanroom process uses DI water, not IPA.
Why this material
Choose Ultem 1000 when a flammability rating is a real requirement, not just a nice-to-have, or when you need a machinable thermoplastic with better impact resistance than PEEK at a lower material cost.
Typical applications
- Aircraft interior components and ducting
- Electrical connector housings and insulators
- Medical device components requiring sterilization
- Food-service equipment parts
- Structural components needing a UL94 V-0 flammability rating
Questions
Why does my Ultem part need special cleaning?
Ultem is sensitive to certain solvents, IPA included, which can cause stress cracking. We substitute a DI-water cleanroom process specifically to avoid this - see the handling notice above.
Is Ultem 1000 the same as PEI?
Ultem is SABIC's trade name for polyetherimide (PEI); Ultem 1000 is the unfilled base grade.
Can Ultem 1000 go into an autoclave?
It tolerates elevated temperature well, but check your specific sterilization cycle against the resin's continuous-use temperature - it's lower than PEEK's.
