FLUOROELASTOMER COMPOUNDS

Abstract:

The present invention is directed to perfluoroelastomer compounds comprising carbon black having a particle size of 100 nm or greater; a mineral filler selected from the group consisting of titanium dioxide, barium sulfate, or a combination of these; a cure site monomer; and a curing agent. These perfluoroelastomer compounds, when cured into articles, exhibit desirable compression stress relaxation properties.
