CarbonX™ HTN+CF [High Temperature Nylon]

CarbonX™ CF-HTN is an advanced semi-aromatic polyphthalamide (PPA) reinforced with high-modulus carbon fiber.  HTN is widely used for metal replacement applications that must resist high mechanical loads at elevated temperatures and aggressive chemical environments.  HTN has traditionally been a go-to material for demanding applications in automotive, aerospace, oil&gas, electrical, electronics, and industrial markets. 

Hardened Nozzles:  Carbon fiber reinforced filaments are abrasive and can wear out a brass or aluminum nozzle.  We recommend our Hardened Steel Nozzles - HERE 

CarbonX™ HTN+CF Thermal Properties

  • Glass Transition (Tg) of 125°C 
  • Melt Temp (Tm) of 260°C 
  • Heat Deflection Temp (HDT) of 195°C

Product Attributes Include:

  • Excellent strength and stiffness over a wide temperature range - up to 195°C [Greater than Ultem™ 9085!]
  • Very low moisture absorption yielding improved retention of mechanical properties when exposed to humid environments
  • Outstanding chemical resistance to alcohols, acids, fuels (auto/jet), oils/lubricants, brake fluid, transmission fluid, antifreeze, and Zn/Ca Chlorides.

Recommended Print Conditions:

  • Extruder:  285-315°C depending on printer
  • Bed Temp:  110 - 120°C
  • Chamber Temp:  80-120°C.  Although not absolutely required, we recommend printing high-performance materials such as our HTN in a printer with a heated chamber.  
  • Bed Prep:  PEI (ULTEM) tape applied to the build plate
  • Hardened Nozzle: 0.4mm or larger recommended.  We strongly recommend our Hardened Steel Nozzles - HERE
  • Layer Height:  Ideal layer height is 60% of nozzle diameter.  We do not recommend printing layers below 0.25mm with carbon fiber grades.  Lower than 0.25mm may create too much back pressure in the hot end and result in poor feeding, jams, drive gear clicking, and eating a notch into the filament.
  • Printing Experience:  PPA is an expert level material and the user should have a significant amount of experience and is using a high-performance or heavily modified printer.
