HPP‑LCF30 · Long Carbon Fiber Reinforced Homopolymer PP
What is PP LCF30 Material?
LFT‑G® HPP‑LCF30 is a high‑performance compound based on homopolymer polypropylene (HPP) reinforced with 30% long carbon fibers. The continuous fiber network delivers exceptional stiffness (tensile modulus > 18 GPa), low density (1.02 g/cm³), and outstanding impact resistance – a direct lightweight replacement for metals and short‑fiber composites.
Its unique architecture ensures superior load transfer, creep resistance, and dimensional stability, making it ideal for structural and semi‑structural applications in automotive, industrial, and sporting goods.

Q: What is the core difference between HPP-LCF30 and PP CF30?
A: HPP-LCF30 retains a long carbon fiber structure that forms a continuous reinforcing network inside the PP matrix. Compared with conventional 30% short carbon fiber PP, it achieves 81% higher flexural modulus, 43% higher notched impact strength, and significantly better creep and fatigue resistance, making it qualified for structural and load-bearing applications.
Q: Can HPP-LCF30 replace aluminum or metal structural parts?
A: Yes. With a density of only 1.02 g/cm³ - 40–50% lighter than aluminum - HPP-LCF30 delivers ultra-high stiffness and dimensional stability. It is a cost-effective lightweight replacement for metal components in automotive, industrial and drone applications, while also eliminating corrosion risk and simplifying assembly.
Q: What key points should be noted in injection molding of HPP-LCF30?
A: To preserve fiber length and maximize final performance, use a low-shear screw (L/D 18:1–24:1), pre-dry the material at 90–100°C for 2–4 hours, set melt temperature at 210–250°C, and avoid excessive back pressure and long residence time. Larger gate and runner dimensions are also recommended.
