Core Viewpoint - FCM is participating in the 2025 Polymer Industry Annual Conference, focusing on innovative solutions for high-voltage lightweight materials in electric vehicles, particularly the PA12 busbar insulation layer material [2][3][7]. Company Overview - FCM specializes in the research and production of high-performance polymer materials, including PPA, PA12, PA66, PA6, PPS, PBT, and PP, and is a leader in the nylon industry in China [2]. - The company holds 15 patents and has successfully operated nearly 800 products, providing comprehensive solutions to customers [2]. - FCM has received multiple honors, including being recognized as a national high-tech enterprise and a provincial innovative small and medium-sized enterprise [2]. Product Introduction - The shift towards high-voltage (800V) and lightweight electric vehicles presents challenges for traditional busbar insulation materials, which struggle with temperature resistance, weight, and processing efficiency [3]. - PA12 is emerging as a potential insulation material due to its excellent overall performance, although it faces challenges in high-temperature resistance and high-voltage insulation reliability [3][7]. - FCM's research on busbar (copper and aluminum) extrusion coating materials shows good adhesion to metals, high elongation, and excellent resistance to chemicals and wear, maintaining high volume resistivity under high temperatures [3][7]. Report Summary - Advances in battery technology necessitate higher conductivity, lower resistance, and better corrosion resistance in busbars to meet the demands of battery systems [7]. - The first generation of PA12 is suitable for battery packs operating at 125°C and 400V, while the second generation is designed for external battery packs at 150°C and 800V [7].
