PEI Filament

TECAFIL PEI - PEI 3D printing filament from Ensinger

Sabic ULTEMTM 9085, otherwise known in our portfolio as TECAFIL PEI 9085 natural filament, is based on the high performance plastic polyetherimide. The ULTEMTM filament has numerous advantageous properties that make this amorphous high performance filament relevant for diverse areas of application. The PEI filament is inherently flame retardant with low smoke emission and therefore meets the FST safety standards (Flame, Smoke and Toxicity).

ULTEMTM is a registered trademark of Saudi Basic Industries Corporation (SABIC).

Our PEI filament portfolio

The ULTEMTM filament available as TECAFIL PEI 9085 natural has high stiffness, excellent dimensional stability and good electrical insulation properties. Our PEI 3D printing filament is tested according to the FST safety standards and is characterised by high resistance to radiation and chemicals. This makes ULTEMTM 9085 filament ideal for applications in the aerospace and tranportation industries, for example.
