For applications requiring extreme stiffness and load-bearing capacity where standard plastics fail, LFT-G® PA6 CF40 (Model: BC04B) stands as the ultimate solution. This is an injection-molding grade Polyamide 6 reinforced with 40% Domestic Long Carbon Fiber, specifically engineered to offer the best cost-to-performance ratio in the market.
While many search for standard PA6 CF40 (Short Fiber), our Long Carbon Fiber (LCF) technology creates a three-dimensional skeletal network inside the part. This structure boosts the flexural modulus to over 22 GPa-approaching the rigidity of die-cast aluminum-while reducing weight by 40%. It is the preferred material for heavy-duty industrial components, robotic arms, and automotive structural inserts.
Why Choose LFT-G® Domestic Grade CF40?
Strategic Cost Advantage without Compromise.
Global supply chains can be volatile. LFT-G® utilizes high-quality domestic T700-grade equivalent long carbon fibers. This ensures:
- Stable Supply Chain: No reliance on fluctuating import quotas.
- Cost Efficiency: Significantly lower price point than imported Toray/Tenax fibers, making high-volume industrial projects financially viable.
- Validated Performance: Rigorously tested to meet ISO mechanical standards for structural integrity.
Performance Highlights: The Power of 40% LCF
Extreme Rigidity (25 GPa+)
With 40% fiber loading, the fiber overlap is dense. This limits polymer chain movement, resulting in a material that resists bending under heavy loads-perfect for metal replacement.
EMI Shielding Capability
The conductive carbon network is dense enough to provide effective Electromagnetic Interference (EMI) shielding, eliminating the need for conductive painting in electronic housings.
Dampening Properties
Unlike metals which transmit vibration, the polymer-fiber matrix dampens vibration naturally. This reduces noise and extends the lifespan of dynamic machinery parts.

Target Applications: Where Stiffness Matters
Processing Note: Handling 40% Fiber Loading
Molding Tip: Due to the high fiber content (40%), the melt viscosity is higher than standard PA6.
- Temperature: Increase mold temperature to 80-100°C to ensure a resin-rich surface and reduce floating fibers.
- Injection Speed: Use medium-to-fast injection speed to fill thin walls before the material freezes, but ensure venting is adequate to prevent burns.
- Drying: PA6 is hygroscopic. Ensure drying at 80°C for 4-6 hours until moisture is <0.2% to prevent hydrolysis.
