The Perfect Spool for High-Temp Applications

The filament's spools are made using PC in order to withstand high-temp materials making them ideal for drying filament once it absorbs moisture. Once the parts are printed with the PEI material, they will resist chemical degradation. This is why it is ideal for automotive and electrical applications.

  • 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
