With the rapid advancement of new energy vehicles (NEVs), power battery systems and electronic control modules demand sealing materials that endure aggressive thermal and chemical conditions. Fluorosilicone rubber, combining the high/low-temperature stability of silicone with the fuel and solvent resistance of fluororubber, is emerging as a preferred material for NEV thermal management systems.

In battery cooling structures, fluorosilicone-based gaskets and thermal pads maintain elasticity from -60°C to +230°C and resist long-term exposure to glycol, phosphate ester coolants, and lithium battery electrolytes. The material's resistance to compression set ensures reliable sealing during continuous thermal cycling.

Fluorosilicone rubber also finds application in wiring harnesses, ECU enclosures, and other electric modules, providing excellent protection against dust, moisture, and vibration. New grades with improved adhesion and lower molding pressure enhance processing efficiency for automated assembly lines.

As NEVs continue to grow, fluorosilicone rubber will remain vital for ensuring thermal safety and reliability across powertrain systems.
