  • Ultem® PEI - Polyetherimide

Ultem® PEI - Polyetherimide

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 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.

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.

Duratron® PEI (Ultem PEI)

High Strength And Heat Resistance, Plus Excellent Dielectric Properties

  • High strength and performs in continuous use to 340°F (170°C)
  • High dielectric strength
  • UL 94-V-0 rated with low smoke
  • Available in glass-reinforced grades

Duratron® PEI will be referred to as Ultem PEI below

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 2300 is a glass–reinforced version (30%, respectively) of Ultem 1000 which provides even greater rigidity and improved dimensional stability while maintaining many of the useful characteristics of basic Ultem. Ultem 1000 is FDA and USP Class VI compliant. FDA compliant colors of Ultem are also available on a custom basis.

Ultem commonly is machined into parts for reusable medical devices, analytical instrumentation, electrical/electronic insulators (including many semiconductor process components) and a variety of structural components requiring high strength and rigidity at elevated temperatures.
