Description

PEI (Polyetherimide) is a high-strength amorphous polymer often branded as ULTEM.

Characterized by excellent heat and flame resistance with a flammability rating of 94-V-0, ULTEM can perform continuously up to 340°F (171°C). ULTEM is also hydrolysis resistant, as well as highly resistant to most acidic solutions.

Additionally, ULTEM has one of the lowest thermal conductivity ratings and the highest dielectric properties of thermoplastic materials, outperforming both Nylon and DELRIN.

Characterized by excellent heat and flame resistance, ULTEM has the highest dielectric strength of any thermoplastic.

ULTEM is commonly used for a variety of structural components requiring high strength and rigidity at elevated temperatures.
