As electric vehicle (EV) powertrains evolve toward higher voltages and thermal loads, conventional rubber materials are increasingly failing to meet the sealing, oil resistance, and heat resistance requirements. Fluorosilicone rubber, with its exceptional resistance to fuels, lubricants, and high temperatures, is becoming the preferred sealing material in critical EV powertrain components.

Leading EV manufacturers have adopted fluorosilicone rubber in sealing rings and gaskets for electric drive systems, gearboxes, cooling systems, and inverters. Its ability to retain elasticity and sealing performance across a wide temperature range—from -60°C to +230°C—makes it especially well-suited for harsh climates and rapid thermal cycling conditions.

Industry analysts predict that as electrification accelerates globally, the use of fluorosilicone rubber in EVs will continue to grow, cementing its role as a key high-performance sealing solution in next-generation vehicles.
