Close Analogs: Formerly SABIC Innovative Plastics Ultem® 1000 PEI.
Key Words: Quadrant Engineering Plastics Products; PEI
Material Notes:
Duratron® U1000 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. Duratron® U1000 is FDA and USP Class VI compliant. FDA compliant colors of Duratron® PEI are also available on a custom basis. Duratron® PEI 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. Data provided by Quadrant Engineering Plastic Products from tests on stock shapes and parts produced by Quadrant EPP.
