Ultem (PEI)

Sheet Rod Tube Film

Ultem Sheet, Rod, Film & Tube

Ultem PEI an amorphous polymer offering continuous performance up to 340°F (170°C). With excellent resistance to flame and heat, Ultem PEI is ideal for high strength/high heat applications, as well as applications requiring consistent dielectric properties over a wide frequency range. Ultem is known as a cheaper PEEK alternative despite having lower impact strength comparatively and a higher temperature threshold.

Ultem PEI is also resistant to hydrolysis, highly resistant to acidic solutions, and capable of withstanding repeated autoclaving cycles. We have Ultem available in sheet, rod, film, and tube for all applications.
