Polyetherimide PEI

PEI is often used in the life sciences or medical technology industry and research as it is resistant to steam, chemicals, and sterilisation, among other things, even when compared to other semi-crystalline thermoplastics.

Polyetherimide (PEI), with the trade name Duratron® U1000, is an amorphous polymer offering high strength and excellent flame and heat resistance. It can withstand up to 340°F (170°C) in continuous service temperature, 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 can withstand repeated autoclaving cycles.

Duratron® U2100, U2200 and U2300 PEI are glass-reinforced versions (10, 20 and 30 % respectively) of Duratron® U1000 PEI, offering even greater stiffness and improved dimensional stability whilst retaining many of the useful properties of the base Duratron® U1000 PEI. Duratron® PEI is FDA- and USP Class VI-compliant. FDA-compliant colours of Duratron® PEI are also available on a bespoke basis.

Polyetherimide (PEI) is typically processed into parts for medical equipment, analytical instrumentation, electrical/electronic insulators (including many semiconductor processing components), and a wide variety of structural components requiring high strength and stiffness at elevated temperatures.
