Fluorosilicone rubber introduces trifluoropropyl groups into its side chains, combining the temperature-resistant elasticity of silicone rubber with the chemical resistance of fluororubber. It exhibits outstanding resistance to swelling by lithium battery electrolyte, with minimal volume change after prolonged immersion and lasting sealing resilience. Thanks to these characteristics, it is widely used as a sealing ring for battery modules, a gasket for battery pack housings, and a waterproof ring for charging ports, serving as a critical sealing material in the safety protection of new energy batteries.
