The Effect of Alternative Fuels on Fluorosilicone Elastomers

Fluorosilicone elastomers are a material of choice for fuel systems designed for use with alternative fuels, such as methanol-gasoline blends. Fuel-immersion results show that not all fluorosilicones behave alike when immersed in methanol-gasoline blends. Information on the specific fluorosilicone being evaluated must be obtained by the fuel-system engineer to make a correct selection.
