Ultem / Lion Engineering Plastics


Ultem™ commonly is machined into parts for reusable medical devices, analytical instrumentation, electrical/electronic insulators (including many semiconductor process components) and a variety of structural components requiring high strength and rigidity at elevated temperatures.

Ultem 1000 

Ultem™ 1000 polyetherimide (PEI) is an amorphous polymer offering high strength and excellent flame and heat resistance. It performs continuously to 340°F (170°C), making it ideal for high strength/ high heat applications, and those requiring consistent dielectric properties over a wide frequency range. It is hydrolysis resistant, highly resistant to acidic solutions and capable of withstanding repeated autoclaving cycles.


Available in Sheet & Rod.

Ultem 2300

Ultem™ 2300 is a 30% glass-reinforced version of Ultem™ 1000 which provides even greater rigidity and improved dimensional stability while maintaining many of the useful characteristics of basic Ultem™. Ultem™ 1000 is FDA and USP Class VI compliant. FDA compliant colors of Ultem are also available on a custom basis. Available in Sheet and Rod.
