Engineers and manufacturers seeking the ultimate balance between lightweight design and structural integrity turn to LFT-G® PA6 CF30. This material is a 30% Long Carbon Fiber reinforced Polyamide 6 (Nylon 6) thermoplastic composite, manufactured using our proprietary pultrusion technology.
Unlike conventional short carbon fiber materials (standard PA6 CF30), the Long Carbon Fiber (LCF) technology allows the fibers to form a skeletal network within the molded part. This internal structure delivers mechanical performance that rivals metals like aluminum and magnesium, making LFT-G® PA6 CF30 the preferred choice for rigorous metal replacement projects in automotive, aerospace, and industrial applications.
Why Choose Long Fiber? The LFT-G® Difference
When searching for PA6 CF30, it is crucial to distinguish between Short Carbon Fiber (SCF) and Long Carbon Fiber (LCF). While both contain 30% carbon content, the performance gap is significant. The longer fiber length in LFT-G® PA6 LCF30 (typically 10mm to 12mm pellets) ensures that the fibers transfer stress more effectively across the polymer matrix.
- Superior Creep Resistance: Maintains shape under constant load, preventing deformation over time.
- Higher Impact Strength: The entangled fiber network absorbs energy efficiently (High Toughness), especially at sub-zero temperatures.
- Enhanced Fatigue Endurance: Ideal for dynamic parts subjected to cyclic vibrations.
Key Properties: Beyond Standard Plastics
Metal-Like Specific Strength
With a density of approx 1.28 g/cm³, it is 75% lighter than steel and 40% lighter than aluminum, yet provides the rigidity required for load-bearing structures.
High Thermal Stability
Long carbon fibers boost the Heat Deflection Temperature (HDT), allowing the material to perform in high-temperature "under-the-hood" environments.
Dimensional Precision
Carbon fibers have a low thermal expansion coefficient. LFT-G® PA6 CF30 exhibits minimal warpage and shrinkage, ensuring tight tolerances.

Application Areas
Processing Guide: Injection Molding LFT
The following values are recommendations. We recommend desiccant / dry air dryers (moisture content below 0.1%). To minimize fiber breakage and ensure optimal performance, a low-compression, general-purpose screw is highly recommended.
| Parameter | Recommendation |
|---|---|
| Drying Temperature | 80 - 100 °C |
| Drying Time | 4 - 6 hours |
| Melt Temperature (Nozzle) ② | 240 - 270 °C |
| Mold Temperature ③ | 60 - 98 °C |
| Back Pressure | Low (0.2 - 0.5 MPa) to minimize fiber damage |
Important Processing Tips:
To preserve the fiber length (which gives the strength), please follow these settings:
- Nozzle: Use a free-flow open nozzle (min. 6mm diameter).
- Gate: Use large Sprue gates (>3mm) to prevent fiber breakage and clogging.
- Screw Speed: Low speed (30-60 rpm) to minimize shear.
- Processing Temp: 260°C - 290°C.
