PEI 9085

PEI 9085 3D Filament, Made using ULTEM™ 9085 PEI
We manufacture this ultra-performance 3D printing filament using ULTEM™ 9085 PEI (polyether imide) resin.  Filaments made from ULTEM™ 9085 resin offers the ability to create parts with excellent properties at elevated temperatures due to a high glass transition temperature (Tg) of 186°C.  PEI is an amorphous, high-performance polymer that combines excellent thermal properties, exceptional dimensional stability, inherent flame retardancy, and good chemical resistance.

Product attributes include:
    • High thermal properties; (Tg) of 186°C
    • Inherent flame resistance with low smoke evolution and low smoke toxicity
    • Long-term hydrolytic stability
    • Excellent dimensional stability (low creep sensitivity and low, uniform coefficient of thermal expansion) and highly reproducible part-to-part dimensions
    • Exceptional strength and modulus, even at elevated temperatures
    • Good resistance to a broad range of chemicals, such as automotive fluids, fully halogenated hydrocarbons, alcohols, and aqueous solutions
    • Stable dielectric constant and dissipation factor over a wide range of temperatures and frequencies

Typical Application Spaces for ULTEM™ PEI:
Aerospace: The excellent balance of flame retardancy, low smoke emission, and low smoke toxicity of ULTEM™ 9085 makes it an excellent candidate for aerospace and aircraft 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 ducts, latches, hinges, food tray containers, door handles, and interior cladding parts.
Automotive / Transportation:  Ultem™ 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 and light enough to replace aluminum in others. For applications like transmission components, throttle bodies, ignition components, sensors, and thermostat housings,
Electrical / Electronics:  ULTEM™ resin 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, FOUP’s, BiTS, PCBs, MCCB internals, Plenums devices, LCD projector internals, fuel cell components, and many other applications.

Filament Specifications:
    • Diameter:  1.75mm (+/- 0.05mm)
    • Colors:  Natural (Light Tan) and Black

Recommended Print Conditions:
    • Extruder Temp: 340 - 370°C
    • Bed Temp: 160-200°C
    • Bed Prep: Rough Borosilicate Glass with PVP gluestick, or high temp carbon fiber sheet plus PVP glue stick, we also recommend the Vision Miner Nano Polymer
    • Print Speed:  Print speeds of 20-30mm/s (starting point), faster as results dictate
    • Enclosure Temp:  90-200°C (Bigger the part higher chamber temps are required)
    • Drying Instructions:  Please dry @110-120°C for 12-24 hours, for the first dry its recommended to dry for atleast 24 hours before using, the drying time can be lowered using a vacuum oven and also storing the filament in a degassing chamber when not in use.
