Benefits of PEKK-A Include:
- Substantially easier to print than PEEK, made using 50/40 type PEKK copolymer known as PEKK-A
- High thermal properties with a Tg of 162°C, HDT of 150°C, and Tm of 305°C
- Inherently flame resistant and self-extinguishing
- Long-term hydrolytic stability making it ideal for steam and autoclave environments
- Excellent dimensional stability with low heat creep, low and uniform coefficient of thermal expansion, and highly reproducible part-to-part dimensions
- Exceptional strength and modulus, even at high 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
Benefits of 3DXSTAT™ Include
- Consistent surface resistivity
- Improved retention of impact & elongation
- Low particulate contamination
- Minimal contribution to outgassing and ionic contamination
Compare 3DXSTAT™ ESD PEKK-A to Stratasys® Antero™ PEKK 840CN03:
- Both use real PEKK-A from Arkema as the base resin component
- Both use carbon nanotubes as the conductive additive
- 3DXSTAT™ ESD PEKK-A is lower cost and suitable for use on lower-pricepoint, open-material 3D printers
- Stratasys® Antero™ 840CN03 is more expensive and only available on the ultra-expensive Fortus® 900mc Plus
Typical ESD PEKK-A Applications Include:
- Semi-con: HDD Components, Wafer Handling, Jigs, Casings, & Connectors
- Industrial: Conveying, Metering, and Sensing Applications
Target Conductivity for 3DXSTAT ESD PEKK-A:
- 10^7 to 10^9 ohm surface resistivity on 3DP sample using concentric ring test method.
- Note: Internal studies have indicated that increased extruder temperatures can achieve higher levels of conductivity. Likewise, lower extruder temperatures have resulted in lower levels of conductivity. Each printer is set-up differently, not to mention varied part geometry. Therefore, expect some trial time to understand how ESD PEKK-A filament works in your specific printer and application.
