ULTEM® High Performance Plastic

ULTEM®, also known as PEI or its full chemical name Polyetherimide is an amorphous plastic that falls into the high performace materials range. ULTEM® can be recognized by its color which is a transparent amber. ULTEM® medical grades are available and include FDA, USP Class VI versions. It is a good choice over polysulfone in applications that require higher strength, stiffness, or temperature resistance.
ULTEM® 1000 is an unfilled PEI and ULTEM® 2300 is reinforced with glass fibers for additional stiffness, tensile strength and dimensional stability.
We stock Ultem® stock shapes from the top US plastics extruders including Ensinger, Rochling, and Quadrant EPP. The total length of Ultem® rod vary based on manufacturer from 48, 60, 96 to 120 inches, but all grades are available in lengths up to 120". If you need a shorter length be sure to let us know. We will cut to size.
