In the evolving landscape of Industrial Materials Science, the shift from traditional metals to advanced thermoplastics is driven by the demand for "Lightweighting" without compromising structural integrity. 40% Long Glass Fiber (LGF) Reinforced Polymers represent the pinnacle of this transition. Unlike Short Glass Fiber (SGF) materials, LGF technology maintains a critical 3D internal skeleton within the molded part, providing exceptional creep resistance and dimensional stability.

At Jurong Best Composite Materials Co., Ltd., we specialize in the pultrusion process that ensures glass fibers remain long and continuous within the resin pellets. This results in products that outperform metals in weight-to-strength ratios, specifically optimized for high-stress industrial environments.

🏢 Corporate Heritage & Manufacturing Prowess

Jurong Best Composite Materials Co., Ltd. is located in the ancient town of Maoshan, which has a history of over a thousand years. The town is part of Jurong City, Zhenjiang, Jiangsu Province. It is situated on the lower reaches of the Yangtze River, adjacent to Nanjing, and is close to Nanjing Lukou International Airport. The Jianning-Taicang Expressway passes through the area, and the Jurong exit of the Shanghai-Nanjing Expressway connects to Zhenjiang Port and Nanjing Port. Benefiting from the radiation of the Yangtze River Delta Economic Zone, the transportation is very convenient.

Core Product Innovation: GFRP Granules

The GFRP granules can make different kinds of special products, such as car parts, washing machine parts, small kitchen electrical appliances, and etc.

Recent milestones include: New GFRP machine line in the workshop starting operation in Nov 2019, matching high-output capacity requests, and multiple International Customer Visits confirming our rigorous quality controlling process for PA6 and PA66 long GFRP.

🌐 Macro Industry Solutions & Global Impact

Automotive Electrification

As EVs demand longer ranges, reducing curb weight is vital. Our 40% LGF-PP and LGF-PA66 are used in battery trays, front-end modules, and pedal boxes, offering metal-equivalent stiffness at 40% less weight.

Industrial Machinery

Replacing zinc and aluminum die-casts in water pump housings and power tool casings. LGF materials provide superior vibration damping and corrosion resistance compared to metallic counterparts.

Renewable Energy

Supporting the infrastructure for solar and wind energy. Our materials offer UV stability and long-term structural endurance for outdoor mounting brackets and connector housings.

🚀 Technical Roadmap & Future Outlook

Phase 1: Interfacial Bonding Optimization (Current)
We are enhancing the chemical coupling agents that bond the glass fiber to the polymer matrix (PP, PA, PPS). This maximizes stress transfer and minimizes micro-cracking under fatigue.

Phase 2: Hybrid Fiber Reinforcement (2024-2025)
Research into LGF + Carbon Fiber hybrids to achieve ultra-high modulus for aerospace applications while maintaining the cost-effectiveness of glass fiber.

Phase 3: Circular Economy & Bio-Resins (2026+)
Integrating recycled LGF content and bio-based Nylon (PA11/12) to meet global ESG requirements and reduce the carbon footprint of manufacturing.

Custom Formulations

Our R&D team offers localized application scenarios tuning—adjusting heat stabilizers or flame retardants (V0, V1, V2) based on specific regional safety regulations.

Professional Q&A: Expert Insights

Why choose 40% LGF over 30% or 50%?

40% is considered the "Sweet Spot" for many structural applications. It offers a significant boost in tensile strength and impact resistance over 30% while maintaining better processability and surface finish than 50% concentrations.

How does LGF improve dimensional stability?

The long fibers form an internal network that restricts the thermal expansion and contraction of the plastic matrix. This results in significantly lower mold shrinkage and less warpage in large, thin-walled parts.

Can these materials be used in high-temperature environments?

Yes, especially when using high-performance matrices like PPS (Polyphenylene Sulfide) or PPA. LGF-PPS can withstand continuous operating temperatures exceeding 200°C while maintaining structural integrity.
