LFT-G® CPP-LCF30 (BC03B) | The Cost-Effective Ultra-Lightweight PP CF30
LFT-G® 30% Long Carbon Fiber PP (Copo Grade)
Historically, PP CF30 was reserved for niche racing or aerospace parts due to cost. LFT-G® CPP-LCF30 (Model: CPP-BC03B) changes the game. By utilizing high-quality Domestic (National) Carbon Fiber, we bring the extreme performance of carbon composites to mass-market industrial and automotive applications.
This grade reinforces a tough Copolymer Polypropylene (Copo-PP) matrix with 30% Long Carbon Fibers. Unlike standard glass-filled PP (density ~1.35 g/cm³), this carbon grade offers an ultra-low density (approx. 0.98 g/cm³), reducing part weight by an additional 20% while doubling the stiffness. It is the ultimate solution for "Lightweighting" strategies where every gram counts, offering electromagnetic shielding (EMI) properties as a bonus.
- √ Ultra-Lightweight: With a density significantly lower than glass-filled nylon or PBT, it offers the highest specific strength (strength-to-weight ratio) in our portfolio.
- √ Cost-Effective Performance: Utilizing domestic carbon fiber supply chains allows for a competitive price point, making metal replacement viable for high-volume parts.
- √ High Impact Copo-Matrix: The Copolymer base resin provides superior impact toughness compared to Homo-PP, preventing brittle failure in cold environments.

Processing Information
The following values are recommendations. We recommend desiccant / dry air dryers (moisture content below 0.1%).
To minimize fiber breakage and preserve carbon fiber length, a low-compression screw is highly recommended.
| Parameter | Recommendation |
|---|---|
| Drying Temperature | 80 - 100 °C |
| Drying Time | 2 - 4 hours |
| Melt Temperature (Nozzle ③) | 220 - 250 °C |
| Mold Temperature (Zone ②) | 40 - 70 °C |
| Back Pressure | Low (to minimize fiber damage) |
