TECAFIL PEI 9085 natural - 1.75 mm

PEI Ultem 9085 filament

The search for an Ultem 3D printing filament usually leads to two types available on the market, PEI Ultem 1010 (or 1000) and 9085. TECAFIL PEI 9085 natural is based on the type Sabic UltemTM 9085 and is an unfilled PEI (polyetherimide) filament.
Ultem 9085 filament is an amorphous high performance polymer with beneficial properties for numerous applications. This Ultem filament can be used to print parts that can withstand high temperatures and high stresses. 
TECAFIL PEI 9085 natural is inherently flame retardant and causes low smoke emission (meets UL94-V0). The combination of these FST (Flame, Smoke and Toxicity) safety standards with outstanding mechanical properties in terms of stiffness, high dimensional stability and high creep resistance over a wide temperature range makes PEI a frequently used material in the transport and aerospace sectors as well as in the automotive industry.
Due to its good electrical insulation properties, Ultem filaments are also very widely used in the electronics and semiconductor industries. Thanks to its good radiation and chemical resistance, PEI 3D printing is also in demand for medical applications.
These characteristics make PEI filaments a suitable material for functional parts, prototypes and production tools. Applications printed with Ultem filament have a continuous temperature resistance of up to 170 °C.
UltemTM is a registered trademark of the Saudi Basic Industries Corporation (SABIC).
