Ultem® 1000 is a thermoplastic polyetherimide high heat polymer designed for injection molding processing. Through the development of new extrusion technology, Ultem® 1000 is produced in a variety of stock shapes and sizes. Compared to PES, PEEK, and Kapton, Ultem® 1000 resin manufactured by SABIC is a cost-effective option with excellent machinability in high heat applications. With continuous use over 340 degrees Fahrenheit, Ultem® 1000 has exceptional flame resistance with a limiting oxygen index and low NBS smoke evolution.

Features of Ultem® Resin

As a more cost-effective option over similar PEI materials, Ultem® 1000 offers excellent machineability in high heat applications. Ultem® 1000 has the capabilities to be thermoformed, extrusion blow molded and injection molded with excellent process abilities.
