PEI Ultem 1000

Name: PEI Ultem 1000
Brand: MatWorld

Verifiedpolymer

PEI Ultem 1000 is a high-performance thermoplastic polyetherimide (PEI) engineering resin known for its exceptional thermal stability, mechanical strength, and chemical resistance across a wide temperature range. It is widely used in aerospace, automotive, and industrial applications where components must withstand elevated temperatures, mechanical stress, and exposure to oils, fuels, and other aggressive chemicals without significant degradation. Engineers select Ultem 1000 over commodity plastics and lower-performance engineering polymers when lightweight construction, dimensional stability in high-heat environments, and long-term durability under demanding conditions are critical design drivers.

Regulatory Screening

Environmental

Safety & Biocompatibility

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
