PEI

PEI (Polyetherimide, also known as ULTEM) filament is an amorphous high-performance super engineering material with excellent heat resistance, high mechanical strength, good flame retardancy and low smoke emission. It offers outstanding dimensional stability and is autoclavable. PEI requires high nozzle temperature and strict drying. Suitable for aircraft interior parts, high-heat electrical components, medical sterilizable parts, food processing equipment and structural high-temperature components.
