ULTEM® is an amorphous high-performance plastic product that is used for medical and chemical instrumentation applications. It is also known as PEI, or polyetherimide, ULTEM’s® chemical name.
At thyssenkrupp Engineered Plastics / Online Plastics® we carry ULTEM® stock shapes from the top US plastics extruders including Ensinger, Rochling, and Quadrant EPP. The total length of ULTEM® rod can vary from 48, 60, 96 to 120 inches, depending on the manufacturer. However, 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.
Unfilled ULTEM® is very recognizable due to its transparent amber color. ULTEM® is also available in a 30% glass fiber filled version. ULTEM® is a viable choice over polysulfone in applications that require higher strength, stiffness, or temperature resistance. In addition, ULTEM® medical grades are available and include FDA, USP Class VI versions. Some other beneficial features of polyetherimide, include:
Visually transparent (unfilled)
Can be continually used up to 340º F
Flame resistant
Very low smoke generation
Unfilled ULTEM® provides excellent dielectric strength
ULTEM® polyetherimide is a valuable high-performance plastic product that is used within the following industrial applications:
Medical instrumentation
Chemical instrumentation
