Ultem PEI — High-Temperature Performance for Aerospace and Medical Devices

  Polyetherimide (PEI, trade name Ultem) is the benchmark for high-temperature performance among specialty engineering plastics. Ultem PEI offers a glass transition temperature of 217°C and long-term service capability above 170°C, while meeting the stringent FAA FAR 25.853 requirements for flammability, smoke, and toxicity in aerospace interiors. In the medical field, medical-grade PEI grades withstand multiple sterilization cycles, with aerospace and medical device end markets projected to grow at 10–13% and 11–14% annually, respectively. resinsplastics.com supplies S-Plastic Ultem PEI resins, including standard flow, high flow, and reinforced grades such as Ultem 1000 and Ultem 2310 (UL94 V0/5VA), suitable for aerospace interior parts, surgical instrument trays, electronic connectors, and high-temperature industrial components. Materials come with COA, RoHS, and MSDS certifications to support customer validation under demanding operating conditions.
