GE Plastics Ultem® 2300 PEI, Polyetherimide, 30% glass reinforced, extruded

Material Notes:
Ultem* 2300 is an extruded 30% glass reinforced polyetherimide. It is an amorphous, high-performance polymer with exceptional flame and heat resistance. It performs continuously to 340°F (171°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 multiple autoclaving cycles.

Ultem 2300 provides greater rigidity and improved dimensional stability while maintaining many of the useful characteristics of unfilled Ultem. Ultem commonly is machined into parts for reusable medical devices, analytical instrumentation, electrical/electronic insulators and a variety of structural components requiring high strength and rigidity at elevated temperatures.
