In aerospace, automotive, and chemical processing, materials used for sealing must endure harsh environments. Fluorosilicone rubber, with its trifluoropropyl side chains, offers both the thermal stability of silicone and exceptional resistance to fuels and solvents, making it ideal for demanding applications.

It operates reliably from -60°C to +230°C, resisting aromatics, alcohols, esters, and ketones. Fluorosilicone rubber is widely used in aircraft fuel system seals, automotive injector O-rings, and defense-grade electronic gasketing. As new energy and advanced manufacturing sectors expand, it also finds applications in EV cable sheaths, railway electronics protection, and hydrogen valve sealing.
