Fluorosilicone
is the common name for fluorovinylmethyl silicone
rubber (see Figure 39).
Fluorosilicones combine the best properties of fluorocarbons and silicones.
Fluorosilicones resist solvents,
fuel, and oil (similar to fluorocarbons).
They also have high and low temperature stability
(as with silicones).
Fluorosilicones are resilient,
with low compression
set characteristics. Though widely used in aerospace
fuel systems and auto fuel emission controls, fluorosilicones
are really only good as static
seals. High friction tendencies,
limited strength, and poor abrasion
resistance disqualify them from dynamic uses.
