Ultem 1000 Unfilled PEI

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. Ultem™ 1000 is FDA and USP Class VI compliant. 

Available in Sheet, Rod, Tube & Film - colors are natural (translucent amber) & black. FDA compliant colors of Ultem are also available on a custom basis.

Ultem 2300

Ultem™ 2300 is a 30% glass-reinforced version which provides even greater rigidity and improved dimensional stability while maintaining many of the useful characteristics of basic Ultem™. 

Ultem 2100 & Ultem 2200

Other glass filled versions of Ultem available are Ultem 2100 10% glass reinforced; and Ultem 2200 20% glass fiber reinforced. These are less common grades and may require minimum runs and longer lead times.

Available in Sheet and Rod - colors are natural & black.
