    ULTEM™ PEI 9085 (Now rebranded as Thermax™) Natural 1.75mm 250gms spool.


    ULTEM™ PEI 9085
    (polyether imide) resin features a high strength-to-weight ratio, high thermal and  chemical resistance, and flame, smoke and toxicity (FST) ratings.

    ULTEM™ 9085 PEI resin is manufactured by Sabic Innovative Polymers and is one of the leading high-performance polymers in the aerospace industry.  This is the same ULTEM™ PEI resin that Stratasys uses for their range of FORTUS 3D printers.

    Filaments manufactured 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
    • 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

    Aerospace Applications: 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 Applications:  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 Applications:  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, PCB’s, MCCB internals, Plenum devices, LCD projector internals, fuel cell components and many other applications.  

    Filament Specifications:

    • Diameter:  1.75mm (+/- 0.05mm)
    • Colors:  Natural

    Recommended Print Conditions:

    • Extruder Temp: 350 - 380°C (all-metal extruder) on packaging displays 340 - 370°C
    • Bed Temp: 140 - 160°C though packaging displays 110 - 120°C
    • Bed Prep: PEI Tape, Polyimide Tape, Lightly sanded FR4 or Perf board.
    • Other:  No cooling fan, Print speeds of 1000mm/min (starting point)

    Annealing Printed Parts:  If needed, parts printed using ULTEM™ PEI may be annealed in a hot-air oven to reduce any printed-in stresses that may be present in the part.  Printed-in stresses may occur in any plastic and may result in lower than expected mechanical properties.  If this is an issue with your part, then you can follow the simple 5-step ramp up/down process for annealing the ULTEM™ parts.

    Step 1:  Place printed parts in cool, room-temp oven.
    Step 2.  Set temp to 300°F and allow to stabilize for 1 hour.  
    Step 3:  After 1 hour at 300°F, increase oven temp to 400°F and allow to stabilize 1 additional hour.  
    Step 4:  After 1 hour at 400°F, reduce heat back to 300°F and allow to stabilize for 30 minutes.  
    Step 5:  After 30 minutes, turn off oven heat and allow printed parts to return to room temp inside the oven as it cools.
