Duratron® PEI

Duratron® Polyetherimide (PEI) is family of transparent amber high-performance polymers that combine high strength and rigidity at elevated temperatures with long term heat resistance. PEI offers excellent dimensional stability combined with broad chemical resistance.  Duratron® PEI grades are commonly 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. Mitsubishi Chemical Group offers Duratron® U1000 PEI and Duratron® U2300 PEI as standard products.
