ThermaX PEI 9085 is a premium filament made using Sabic’s ULTEM 9085 resin. This resin is FAA approved for FST (Flame/Smoke/Toxicity) applications and meets FAR 25.853 and OSU 65/65 standards.

ThermaX PEI 3D printing filament, made using ULTEM 9085 PEI

We produce this ultra-high performance 3D printing filament using Sabic’s ULTEM 9085 PEI (polyether imide) resin. Filaments made with ULTEM 9085 resin offer the ability to create parts with excellent properties at elevated temperatures thanks to a high glass transition temperature (Tg) of 186°C.

PEI is a high-performance amorphous polymer that combines excellent thermal properties, exceptional dimensional stability, inherent flame retardancy and good chemical resistance.

The benefits of PEI 9085 include:

• High thermal properties, with a Tg of 186°C
• Inherently flame resistant with low smoke evolution and low smoke toxicity
• Long-term hydrolytic stability
• Excellent dimensional stability, low sensitivity to thermal creep, and a very low and uniform coefficient of thermal expansion create highly reproducible part-to-part dimensions.
• Exceptional strength and modulus, even at high temperatures
• Good resistance to a wide range of chemicals, including automotive fluids, fully halogenated hydrocarbons, alcohols and aqueous solutions
• Stable dielectric constant and dissipation factor over a wide range of temperatures and frequencies

Typical applications of ULTEM 9085 PEI:

Aerospace:

ULTEM 9085’s excellent balance of flame retardancy, low smoke, and low smoke toxicity makes it an excellent candidate for aerospace and aviation applications. ULTEM 9085 meets FAR 25.853 and OSU 65/65 with low toxicity, smoke, and flame evolution. Ultem resins are found in applications such as personal service units, oxygen panels and components, ventilation system components, connectors, cable trays, closures, hinges, food tray containers, door handles, and interior trim parts.

Automotive and transportation sector:

ULTEM resins provide automotive manufacturers with a high-performance, chemically resistant, thermally stable and cost-effective metal alternative that is strong enough to replace steel in some applications but light enough to replace aluminum in others. For applications such as transmission components, throttle bodies, ignition components, sensors and thermostat housings.

Electronics:

ULTEM resin can be an excellent material choice for today's demanding electrical applications, including connectors, MCB components such as housings, shafts and levers, hard disk drive internals, FOUP, BiTS, PCBs, MCCB internals, Plenum devices, LCD projector internals, fuel cell components and many other applications.

Recommended print settings:

• Extruder: 350-380°C
• Bed temperature: 140-160°C
• Bed preparation: nanopolymer adhesive or 3DXTECH polyimide tape
• Other: No cooling fan with 16mm/s print speed as a starting point
• Heated chamber: Recommended, a chamber helps reduce warpage and improves layer adhesion
• Holders: ThermaX HTS High Temperature Holder is ideal for complex, high temperature materials just like this.
• Drying instructions: 120°C for 4 hours.
