Ultem 1000 Technical Property Data
Ultem* l000 polyetherimide
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 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.
