ThermaX™ PEI 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
