ABSTRACT:
A fluoropolymer gum of 60 to 85 mol percent vinylidene fluoride, 10 to 40 mol percent of hexafluoropropene and 0.15 to 3 mol percent 1-bromo-2,2-difluoroethylene is provided which can be blended with fluorosilicone gum and 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, coupled with good physical properties such as high tensile strength and elongation.
