The ULTEM™ family of amorphous thermoplastic polyetherimide (PEI) resins offers outstanding elevated thermal resistance, high strength and stiffness, and broad chemical resistance. ULTEM combines exceptional strength and rigidity with excellent thermal properties, including outstanding heat resistance under continuous operating temperatures of 340°F (170°C). In addition, ULTEM offers exception electrical properties over several different frequencies. 

These characteristics, together with ease of machining and secondary fabrication, make ULTEM ideal for use in applications in the Aerospace and Transportation, Electronics, and Oil and Gas Industries. Our ULTEM™ 1000 is made in the United States using 100% prime virgin material and we offer variety of outer diameters (OD) from 3/8" inches (0.375") to 6" inches (6.00"), all in stock online at the best prices.
