Abstract
The present invention describes uncured fluorocarbon elastomer base compositions and cured fluorocarbon elastomer compositions comprising a fluorocarbon elastomer, an amorphous silicone resin, and optionally a polydiorganosiloxane gum or a hydrocarbon polymer elastomer. The cured fluorocarbon elastomers typically contain additional components such as an acid acceptor, a cure agent, and a filler. The cured compositions have high strength, low temperature flexibility, high solvent resistivity, and low fuel permeability.
