High strength plastic with outstanding electrical and high service temperature properties
Ultem® (polyetherimide) is a semi-transparent high strength plastic material that can operate in high service temperature environments. Ultem® is resistant to hot water and steam and can withstand repeated cycles in a steam autoclave. FDA compliant grades of Ultem® are available. For Ultem® chemical resistance view our chart.
Ultem® has outstanding electrical properties, with one of the highest dielectric strengths of any thermoplastic material.

Ultem® Properties and Material Options
Utem® 1000– Unfilled or unreinforced 1000 series plastics are translucent amber in color and combine exceptional mechanical, thermal, and electrical properties.
Glass-Filled Utem® 2300– The addition of glass fiber reinforcement in the 2000 series, enhances tensile strength, stiffness, and overall dimensional stability.
Tech Tip– Ultem® is often used instead of polysulfone when superior strength, stiffness, or temperature resistance is required.
