Recently, Sichuan FCLEP New Material Co., Ltd. (hereinafter referred to as "FCLEP") announced the successful development of a high-performance polyamide (PA) series material specifically designed for insulation cladding of copper and aluminum busbars in new energy vehicles. The series covers four major categories: PA612, PA12, PA1012, and high-transparency nylon. These products comprehensively benchmark international first-tier brands in key indicators such as processing fluidity, mechanical strength, electrical insulation, and heat aging resistance. They have passed stringent verification from multiple leading battery manufacturers and electric drive system suppliers and have achieved batch applications.
With the popularization of 800V high-voltage platforms and high-power electric drive systems, new energy vehicles have raised higher requirements for busbar cladding materials. They must combine excellent CTI (Comparative Tracking Index ≥600V), low moisture absorption (<1.5%), high dimensional stability, and good injection molding encapsulation capability. Leveraging independent formula design and modification technology, FCLEP has successfully addressed pain points of traditional PA materials such as easy deformation and electrical performance degradation in high-temperature and high-humidity environments. Its PA612 and PA1012 products are particularly suitable for one-time injection molding of complex-structured copper busbars, with a flow length ratio exceeding 150:1; transparent nylon meets customer requirements for high resistance, high chemical resistance, temperature resistance above 150°C, while maintaining UL94 V-0 flame retardant rating for components.
Currently, this series of materials has been successfully applied in multiple customers' liquid-cooled electronic control units, battery module connectors, and OBCs (On-board Chargers). FCLEP stated that it will continue to deepen the "Material-Component-System" collaborative development model, accelerate the deployment of bio-based PA in the field of electrical connections, and contribute to the independent control and green upgrading of high-performance engineering plastics in China's new energy industry chain.
