Fluorosilicone rubber brilliantly combines the advantages of silicone and fluororubber. It not only retains the excellent high and low-temperature resistance of silicone materials but also exhibits superior resistance to oil, aviation fuel, and chemical solvents, thanks to the fluorinated groups introduced into its side chains. Within a broad temperature range of -60°C to 200°C, it is one of the few elastomers capable of resisting non-polar media. It is widely used in aerospace fuel system seals, automotive engine components, and precision instrument protection. IOTA FLSR3400 addition-type liquid fluorosilicone rubber
