Fluorosilicone compound has recently made significant technological advancements in the field of new energy vehicle battery system encapsulation. Through precise formulation design and optimized mixing processes, this material successfully achieves deep integration of the excellent media resistance of fluorosilicone rubber with the superior processing characteristics of compounds, providing innovative solutions for the safe sealing and long-term protection of power battery modules, becoming one of the key materials ensuring the safe operation of new energy vehicles.

Research data shows that fluorosilicone compound maintains stable physical properties within a wide temperature range of -60℃ to 200℃, with its volume expansion rate in coolants and electrolytes reduced by over 70% compared to traditional materials. Through optimization of filler systems and curing processes, the material achieves tensile strength of 9.0-11.5 MPa and maintains excellent tear strength levels of 38-48 kN/m. Accelerated aging tests indicate that after 1,000 hours of aging at 150°C, the material retains over 85% of its mechanical properties, demonstrating exceptional long-term reliability.

In the new energy vehicle sector, fluorosilicone compound has been comprehensively applied in module encapsulation for ternary lithium batteries and lithium iron phosphate batteries. Actual measurement data shows that battery modules sealed with this material reduce electrolyte leakage by more than 90% compared to traditional solutions during multiple rigorous tests simulating collisions, vibrations, and thermal shock. Particularly in thermal runaway propagation tests, the material successfully extends thermal spread time to more than three times the industry standard requirements, providing valuable time for battery system safety warnings and emergency responses.

With the rapid development of 800V high-voltage platforms and ultra-fast charging technologies, fluorosilicone compound demonstrates unique advantages in handling high-voltage and high-current operating conditions. The newly developed high thermal conductivity version improves thermal conductivity to 0.6 W/(m·K) while maintaining excellent sealing performance, effectively enhancing the heat dissipation of battery modules. Meanwhile, through process innovation, material suppliers have achieved low VOC emissions in the production process, with products complying with the world's most stringent automotive interior air quality standards.

Industry experts note that the technological breakthrough of fluorosilicone compound not only enhances the intrinsic safety level of power battery systems but also provides crucial material support for the sustainable development of the new energy vehicle industry. With the accelerated commercialization of solid-state battery technology, research and development work on fluorosilicone compounds compatible with next-generation battery systems is fully underway, and large-scale application in high-end new energy vehicles is expected within the next three years.
