High Performance Polymers

Ultrafuse® PEI 9085


General Information

The Ultrafuse PEI 9085 filament is made from ULTEM 9085 resin.* This amorphous thermoplastic is a Polyetherimide (PEI) blend developed for its higher flow properties, offering outstanding printing behavior, high thermal resistance, strength and stiffness and broad chemical resistance. Due to the unique properties, this
material is a great addition to our high-performance portfolio. Utrafuse PEI 9085 is developed for demanding applications and high-temperature environments like aerospace or automotive. Because of its inherent flame retardancy and low smoke emission, it is well suited for electronics and electrical appliances.
