Materials - Ultem® PEI

For the ultimate performance in high-heat/high-strength applications

One of the most frequently used high-performance materials on the market, Ultem PEI combines exceptional strength and rigidity with excellent thermal properties, including outstanding heat resistance under continuous operating temperatures of 340°F (170°C). For increased rigidity, Ultem PEI can be reinforced with glass fiber.

In addition, Ultem PEI offers consistent electrical properties across a wide range of frequencies. These attributes, coupled with ease of machining and fabrication, makes Ultem PEI ideal for use in a multitude of high heat/high strength applications within the medical, pharmaceutical, aerospace and electronics industries.
