LFT-G® CPP-LCF40 (BC04B) | The Conductive & Ultra-Stiff PP CF40
LFT-G® 40% Long Carbon Fiber PP (Copo Grade)
Looking for high-modulus PP CF40 material? LFT-G® CPP-LCF40 (Model: CPP-BC04B) is a premium composite that pushes the boundaries of Polypropylene. By reinforcing a tough Copolymer PP matrix with 40% Long Carbon Fibers, we create a material that is not only ultra-lightweight but also electrically conductive.
Engineered for extreme performance, our pellets are designed to replace metals (aluminum, magnesium) and expensive engineering plastics like PA66-GF. The Copo-PP base ensures high impact toughness, while the dense carbon fiber network provides exceptional creep resistance and natural EMI Shielding, making it ideal for automotive electronics and aerospace components.
- √ Superior Skeletal Network: LFT technology ensures fibers remain long within the matrix, forming a skeleton that prevents crack propagation and boosts impact strength by 2-3x over short fiber CF40.
- √ Excellent EMI Shielding: The high 40% carbon content creates a conductive path, providing effective electromagnetic interference shielding for sensitive electronics.
- √ Dimensional Stability: Exhibits extremely low shrinkage and warpage, ensuring precision tolerances in large structural parts like instrument panel carriers.

Processing Information
The following values are recommendations. We recommend desiccant / dry air dryers (moisture content below 0.1%).
To minimize carbon fiber breakage, use a low-compression screw and avoid high back pressure.
| Parameter | Recommendation |
|---|---|
| Drying Temperature | 80 - 100 °C |
| Drying Time | 2 - 4 hours |
| Melt Temperature (Nozzle ③) | 220 - 260 °C |
| Mold Temperature (Zone ②) | 40 - 70 °C |
| Back Pressure | Very Low (preserve fibers) |
