Duratron® PEI (Ultem PEI)
High Strength And Heat Resistance, Plus Excellent Dielectric Properties -
Duratron® PEI will be referred to as Ultem PEI below
Ultem 1000 Polyetherimide (PEI) - is an amorphous polymer offering high strength and excellent flame and heat resistance. It performs continuously to 340°F (170°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 repeated autoclaving cycles.
Ultem 2300 is a glass–reinforced version (30%, respectively) of Ultem 1000 which provides even greater rigidity and improved dimensional stability while maintaining many of the useful characteristics of basic Ultem. Ultem 1000 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 (including many semiconductor process components) and a variety of structural components requiring high strength and rigidity at elevated temperatures.
