Explore our highly certified high-performance long fiber granules configured with superior aspect ratio retention for complex injection molding applications.
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 (from Nanjing to Taicang) 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, our shipping logistics and domestic fast-transit networks are incredibly efficient.
Unlocking mechanical performance ceilings by preserving the structural aspect ratio of internal fiber frameworks.
In high-stress thermoplastic design, structural failure often originates from microscopic crack propagation. Traditional Short Fiber Thermoplastics (SFT), despite being easy to process, typically limit fiber lengths to less than 1.0 mm post-injection. Under severe mechanical stress, these short fibers fail to act as cohesive internal scaffolding. The structural framework breaks down as the load transfers primarily to the weak polymer matrix.
By contrast, Long Fiber Reinforced Thermoplastics (LFRT) maintain an internal fiber skeleton where fiber lengths range between 10 mm and 12 mm. This crucial aspect ratio ($L/D > 100$) forces mechanical loads to disperse along continuous structural channels. Rather than fracturing, the interwoven fiber network absorbs dynamic kinetic impacts, providing high structural damping capacity and significant dimensional stability under extreme temperatures.
Long fiber composites retain mechanical resilience at sub-zero temperatures (down to -40°C), preventing the brittle micro-fractures common in short-glass structures.
Continuous loading results in minimal creep deformation over long periods, making LFRT the ideal choice for heavy automotive brackets and industrial components.
LFRT drastically reduces thermal shrinkage rates and isotropic warpage, ensuring high-precision structural tolerance in extreme injection processes.
Leveraging tailored polymers to secure optimal tensile, flexural, and thermal performance across diverse application landscapes.
