PEEK Manufacturer Plastics Long Carbon Fiber Plastic Compounds

What Is PP LCF?

Our PP (Polypropylene) composite reinforced with continuous long carbon fibers (LCF) combines lightweight density, excellent stiffness, and enhanced mechanical strength with superior chemical resistance. This material is designed for applications that demand cost-effective performance, weight reduction, and long-term durability across automotive, industrial, and consumer markets.

Technology Behind the Strength
Continuous Long Carbon Fiber Reinforcement
Unlike short fiber composites, our PP-LCF materials use long carbon fibers (typically 12–25 mm) carefully embedded during compounding and molding. This extended fiber length forms a robust internal network that significantly improves tensile strength, flexural modulus, and impact resistance compared to short fiber PP.

Advanced Pultrusion & Compounding Techniques
Through precision pultrusion and compounding, long carbon fibers are uniformly distributed in the PP matrix with strong interfacial bonding and minimal fiber damage. This ensures consistent mechanical performance, reliable processing, and repeatable high-quality parts.

Thermal and Chemical Resistance
Polypropylene offers low density, good fatigue resistance, and outstanding chemical resistance to acids, bases, fuels, and most industrial solvents. When reinforced with long carbon fibers, PP-LCF delivers excellent stiffness and mechanical reliability under demanding service conditions, even in aggressive chemical environments.

Dimensional Stability and Creep Performance
Compared with unfilled PP, long carbon fiber reinforcement dramatically reduces creep and thermal expansion, enhancing dimensional stability, rigidity, and load-bearing capability, especially in precision and structural applications.

Where It Works Best
Automotive & Transportation
Interior and exterior structural parts requiring lightweighting and impact resistance
Seat structures, instrument panel supports, underbody shields, and semi-structural housings

Industrial & Electrical Equipment
Load-bearing housings, tool handles, and components needing strength-to-weight efficiency
Parts exposed to chemicals or solvents where corrosion resistance is vital

Consumer Goods & Sporting Equipment
Lightweight yet durable parts in luggage, high-end sporting gear, and appliances
Components that benefit from rigidity without sacrificing cost-effectiveness

Logistics & Packaging Applications
Pallets, crates, and containers where stiffness, impact resistance, and long service life are critical
