Fluorosilicone compound has recently achieved significant technological advancement in the field of new energy vehicle battery system encapsulation. Through precise formulation design and optimized mixing processes, this material successfully combines the electrolyte resistance of fluorosilicone rubber with the excellent processing characteristics of compounds, providing an innovative solution for the safe sealing and long-term protection of power battery modules. It has become a key material ensuring the safe operation of electric vehicles.

Research data indicates 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 high-performance tear strength levels of 38-48 kN/m. Long-term aging tests show that after 1,000 hours of aging at 150°C, the material retains over 85% of its mechanical properties, demonstrating exceptional durability.

In the new energy vehicle sector, fluorosilicone compound has been widely applied in module encapsulation for ternary lithium batteries and lithium iron phosphate batteries. Actual test 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 volatile organic compound emissions during production, with products complying with stringent global 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.
