Polypropylene (PP), also known as polypropene, is a semi-crystalline thermoplastic polymer. It features low density, excellent chemical resistance, good heat resistance, fatigue durability, and reliable electrical insulation properties.
Neither homopolymer nor copolymer PP is universally superior. The optimal choice depends on the application.
Homopolymer PP provides higher stiffness and strength, while copolymer PP offers improved toughness, impact resistance, and corrosion resistance. When reinforced with fibers, copolymer PP exhibits better fiber–matrix adhesion, making it more suitable for long fiber reinforcement systems.
Long carbon fiber reinforced thermoplastics are ideal for applications where short fiber materials cannot meet performance requirements or where metal replacement is required.
These composites provide lightweight structures, high modulus, high specific stiffness, and low thermal expansion. Long fibers form a continuous internal network, significantly enhancing mechanical performance.
Xiamen LFT’s long carbon fiber reinforced PP materials are widely used in automotive interior and exterior parts, especially for lightweight new energy vehicle applications.

To effectively reinforce thermoplastics, fiber length must exceed the critical fiber length. For polypropylene, this critical length is approximately 3.1 mm.
Xiamen LFT’s long fiber thermoplastic technology ensures initial fiber lengths of around 10 mm and optimized injection molding processes, maintaining effective fiber length in final parts.
Xiamen LFT Composite Plastic Co., Ltd., established in 2009, is a global supplier of long fiber reinforced thermoplastic materials integrating R&D, manufacturing, and international marketing.
Our products are certified under ISO 9001 and IATF 16949 systems and are widely used in automotive, aerospace, military components, new energy, medical equipment, wind power, and sports equipment.
