CarbonX™ HTN+CF (High Temp CF Nylon) Printing Filament
CarbonX™ High Temp CF Nylon is an advanced, true semi-aromatic polyphthalamide (PPA) reinforced with high-modulus carbon fiber. This polymer 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.

Benefits of HTN+CF High Temp CF Nylon Include:
- High thermal properties, with a Tg of 125°C, HDT of 240°C, and Tm of 265°C
- Excellent strength and stiffness over a wide temperature range, up to 240°C, higher than ULTEM™ PEI
- Very low moisture absorption yielding improved retention of mechanical properties even when exposed to humid environments
- Outstanding chemical resistance to alcohols, acids, automotive and jet fuels, oils, lubricants, brake and transmission fluids, antifreeze, and Zn/Ca Chlorides
Filament Specifications:
1.75mm and 2.85mm +/- 0.05mm in diameter

Carbon Fiber Reinforced Filament
What Is It?
Fibers 5-10 micrometers wide made of carbon. The fibers are aligned following the axis of the material.
This, along with their physical makeup, are what give this material its excellent properties.
What Does It Do?
Carbon Fibers demonstrate a lot of desirable material properties:
- High stiffness
- High tensile strength
- High heat tolerance
- High chemical resistance
- Low weight
- Low thermal expansion
How Does It Work?
Reinforcing plastic with carbon fibers produces a 3D printing filament which exhibits the best properties of both the carbon fibers and the plastic of choice.
What Is It Good For?
Ideal for any applications which require light weight and rigidity.
Carbon fiber reinforced parts, designed to use less material and save weight, is extremely popular in aerospace, civil engineering, the military, and motorsports.
Abrasive Material
This material is particularly abrasive among 3D printing filaments. Users may find standard brass nozzles are chewed through very quickly compared to standard wear and tear. When worn through, the nozzle diameter will widen inconsistently and the printer will experience extrusion issues.
Because of this, it's strongly recommended this material be printed through a hardened steel nozzle rather than a softer metal. Hardened steel nozzles can often be inexpensive and easily installed depending on your printer manufacturer's instructions.
