Industrial-grade long glass fiber reinforced polymer granules
Located in the historic ancient town of Maoshan, Jurong City, within the Yangtze River Delta Economic Zone, Jurong Best Composite Materials Co., Ltd. stands as a beacon of innovation in the composite materials industry. Our strategic location near Nanjing Lukou International Airport and major expressways ensures seamless global logistics for our international partners.
We specialize in the R&D and manufacturing of Long Glass Fiber Reinforced Polypropylene (LGF-PP), PA6, PA66, and other high-performance thermoplastics. Our mission is to offer the best quality products that drive efficiency in the automotive, appliance, and structural engineering sectors.
The global shift toward lightweighting and sustainability has positioned Long Glass Fiber Reinforced Polypropylene (LGF-PP) as a critical material in modern manufacturing. Unlike traditional short glass fiber (SGF) reinforced plastics, LGF-PP granules maintain a fiber length equivalent to the pellet length (typically 10mm to 25mm). This structural integrity creates a 3D internal fiber skeleton that significantly enhances mechanical properties.
In the Automotive sector, LGF-PP is replacing metal components and more expensive engineering plastics like PA66. The global market is expanding at a CAGR of over 7.5%, driven primarily by the Electric Vehicle (EV) revolution where every kilogram saved translates to increased range and battery efficiency.
Enterprises are shifting from high-cost European sources to China-based manufacturers that offer comparable E-E-A-T standards with significantly higher factory efficiency.
LGF-PP's 100% recyclability and low specific gravity (0.9-1.2 g/cm³) make it the "green" choice for future-proofed industrial designs.
Excellent creep resistance and high fatigue strength allow LGF-PP to perform under extreme thermal and mechanical stress environments.
As a leading China Long Glass Fiber Reinforced PP Granules Manufacturer, we leverage an integrated supply chain that spans from raw polymer synthesis to advanced pultrusion lines. Our recent workshop expansion featured new GFRP machine lines that maximize output while maintaining strict tolerances.
China's manufacturing edge is no longer just about cost—it is about speed to market and technical customization. We offer:
| Property | Short Glass Fiber PP | Long Glass Fiber PP (LGF-PP) | Advantage |
|---|---|---|---|
| Tensile Strength | ~100 MPa | ~150+ MPa | 50% Improvement |
| Impact Strength | ~10 kJ/m² | ~25-30 kJ/m² | Superior Durability |
| Flexural Modulus | 5000 MPa | 9000+ MPa | Higher Rigidity |
| Heat Deflection (HDT) | 145°C | 160°C | High Temp Stability |
Front-end modules, battery trays, instrument panel carriers, and sunroof tracks. Our LGF-PP provides the requisite energy absorption for crash safety.
Washing machine drums, pump housings, and dishwasher components. Resistance to hot water and detergents is a core material benefit.
Housing for drills and saws. LGF-PP offers the tactile feel of premium plastics with the impact resistance of magnesium alloys.
The trend is moving toward hybrid composites. By combining Carbon Fiber with Long Glass Fiber (LCF+LGF), manufacturers are achieving unprecedented strength-to-weight ratios. Furthermore, the integration of bio-based Polypropylene is becoming a requirement for European procurement tenders.
Modern procurement directors look beyond price. They seek Information Gain—meaning detailed data sheets, CAE mold flow analysis support, and batch-to-batch consistency. Our factory provides full technical transparency, ensuring that "Made in China" represents "High-Tech Engineering."
