How to CNC Machine PEI (Ultem) for High-Temperature Applications?
Introduction When your application demands materials that withstand extreme heat without sacrificing strength, PEI (Ultem)—Polyetherimide—stands out. This high-performance thermoplastic maintains its properties at continuous use temperatures up to 180°C, far beyond what most engineering plastics can handle. It is biocompatible, chemically resistant, and electrically insulating. Aerospace components, medical devices, and industrial machinery all rely on […]
