<p>A blend of (a) 90 to 20 parts fluoropolymer gum of 60 to 85 mol percent vinylidene fluoride, 10 to 40 mol percent of hexafluoropropene and 0.15 to 3 mol percent bromine-containing olefin, and (b) 10 to 80 parts fluorosilicone gum can be vulcanized in presence of free-radical initiators to produce elastomeric vulcanizates with desired balance of chemical solvent or fluid resistance, high temperature stability, and low temperature flexibility. </p> |
