CarbonX™ PEI CF [Aerospace] is made using Sabic Ultem™ 9085 PEI (polyether imide) and Toray Torayca™ T800 Aerospace-grade carbon fiber. Toray’s T800 aerospace-grade carbon fiber offers excellent strength and stiffness and couples excellently to Ultem™ 9085 – creating an outstanding material with excellent flammability, thermal, mechanical, and chemical resistance properties.

Product attributes include:

• High thermal properties, Tg of 186°C and an HDT of 165°C
• Inherent flame resistance due to Ultem™ 9085 base resin
• Improved stiffness and strength for structural applications
• Excellent dimensional stability – lower CTE, warp, and shrinkage vs unfilled grades
• Resistance to a broad range of chemicals, include automotive fluids, fully halogenated hydrocarbons, alcohols, and aqueous solutions

Aerospace:

The excellent balance of flame retardancy, low smoke emission, and low smoke toxicity of ULTEM PEI CF makes it an excellent candidate for aerospace and aircraft applications. ULTEM offers 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 ducts, latches, hinges, food tray containers, door handles, and interior cladding parts.

Automotive & Transportation:

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

Electronics:

PEI CF may be an excellent material choice for today’s demanding electrical applications, including connectors, MCB components like housings, shafts and levers, hard disk drive internals, FOUPs, BiTS, PCBs, MCCB internals, Plenum devices, LCD projector internals, fuel cell components, and many other applications.

Filament Specifications:

• Diameter:  1.75mm ( /- 0.05mm)
• Color:  Black

Recommended Print Conditions:

• Extruder Temp: 365 - 390°C (all-metal extruder)
• Bed Temp: 140 - 160°C
• Bed Prep: , PEI tape, Polyimide Tape, Lightly sanded FR4 or Perf board.
• Nozzle: We strongly recommend a 0.4mm orifice or larger using Hardened Steel Nozzles - found 
• Layer Height:  Ideal layer height is 60% of nozzle diameter.  We do not recommend printing layers below 0.25mm with carbon fiber grades.  Lower than 0.25mm may create too much back pressure in the hot end and result in poor feeding, jams, drive gear clicking, and eating a notch into the filament.
