LFT-G® CPP-LCF50 (BC05B) | The Ultimate Metal Replacement PP CF50
LFT-G® 50% Long Carbon Fiber PP (Copo Grade)
When standard plastics fail and aluminum is too heavy, LFT-G® CPP-LCF50 (Model: CPP-BC05B) is the answer. This is the pinnacle of our Polypropylene line, reinforced with a massive 50% Long Carbon Fiber content. By utilizing a high-impact Copolymer PP matrix, we prevent the brittleness often associated with such high fiber loading.
Designed for extreme metal replacement, this PP CF50 grade offers a flexural modulus exceeding 28 GPa-rivaling die-cast magnesium and aluminum alloys. It allows engineers to design ultra-thin, rigid structural parts that are 50% lighter than steel, with intrinsic EMI shielding and zero corrosion issues.
- √ Ultimate Specific Stiffness: With a density of only ~1.22 g/cm³, it offers the highest stiffness-to-weight ratio in its class, surpassing traditional metals.
- √ Cost-Effective Domestic Carbon: Leveraging high-quality national carbon fiber supply chains to make high-volume automotive and industrial applications commercially viable.
- √ EMI & Static Discharge: The dense carbon network creates a highly conductive path (10² Ω), perfect for housing sensitive electronics without extra coating.

Processing Information
The following values are recommendations. We recommend desiccant / dry air dryers (moisture content below 0.1%).
Due to high fiber content, use wear-resistant barrels/screws and larger gate sizes to prevent clogging.
| Parameter | Recommendation |
|---|---|
| Drying Temperature | 90 - 110 °C |
| Drying Time | 2 - 3 hours |
| Melt Temperature (Nozzle ③) | 230 - 270 °C |
| Mold Temperature (Zone ②) | 50 - 80 °C |
| Back Pressure | Very Low (preserve fibers) |
