ThermaX PEI-GF10


  • £65.00

ThermaX™ PEI-GF10 Glass Fibre Reinforced 3D Filament, Made using ULTEM™ PEI

We manufacture this ultra-performance 3D printing filament using 10% glass fibre reinforced ULTEM™ PEI (polyether imide) resin.  PEI is an amorphous, high-performance polymer that combines excellent thermal properties, exceptional dimensional stability, inherent flame retardancy, and good chemical resistance.  The addition of glass fibre adds stiffness, strength, thermal properties, and enhanced dimensional stability.  Filaments made using ULTEM™ PEI resin offer the ability to create parts with excellent properties at elevated temperatures due to a high glass transition temperature (Tg) of 217°C.  

Product attributes include:

  • High thermal properties: Tg of 217°C, HDT of 210°C
  • Inherent flame resistance
  • 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
