Ultem 1000 Technical Property Data
Ultem 1000 polyetherimide is an amorphous, high-performance polymer with exceptional flame and heat resistance. It performs continuously to 340F (171C), 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 100 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 and a variety of structural components requiring high strength and rigidity at elevated temperatures.
