Fluorosilicones (FVMQ) combine most of the attributes of silicone with resistance to petroleum oils & hydrocarbon fuels typical in Fluoroelastomers. As a result, they are often used in aircraft fuel systems.

 

Low physical strength and poor abrasion resistance combined with high friction, usually limit Fluorosilicone to use as static seals.  Fluorosilicones are suitable for use over a temperature range of -85° to 350°F (-65° to 175°C).

 

PAI offers Fluorosilicone compounds in a hardness range of 40 to 80 durometer. Blue is the standard color but others are available.
