Made using Arkema Kepstan® PEKK (PolyEtherKetoneKetone) and state of the art conductive additives, this ESD-safe PEKK is one of the highest-performance polymers in world and ideal for demanding applications in aerospace, defense, automotive, and electronics applications.  

Aerospace-Grade Performance.  This filament was created for the most demanding applications where tightly controlled static dissipation, thermal properties, mechanical performance, low outgassing, and chemical resistance properties are required.  

3DXSTAT™ ESD PEKK-A product attributes include:

  • Made using the 60/40 type PEKK copolymer (PEKK-A)
  • Substantially easier to print than PEEK
  • Glass Transition Temp (Tg) of 162°C (20°C higher than PEEK)
  • Heat distortion temperature (HDT) of 150°C
  • Melt Temp (Tm) of 305°C  (allows for lower print temps than PEEK)
  • 10^4 to 10^9ohm surface resistivity on 3DP sample using concentric ring test method
  • Consistent surface resistivity and low particulate contamination
  • Low outgassing - ideal for space related applications
  • PEKK has inherent flame resistance
  • Long-term hydrolytic stability in steam and autoclave environments
  • Excellent dimensional stability (low creep and low/uniform coefficient of thermal expansion) allowing for highly reproducible part-to-part dimensions
  • Exceptional strength and modulus, even at elevated temperatures
  • Excellent 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

Filament Specifications:

  • Diameter:  1.75mm (+/- 0.05mm)

Recommended Print Conditions:

  • Extruder Temp:  355 - 385°C 
  • Bed Temp: 120 - 140°C
