Tetrafluoroethylene, propylene, optionally vinylidene fluoride, i) trifluoroethylene, ii) 3,3,3-trifluoropropene-1, iii) 1,2,3,3,3-pentafluoropropylene Iv) a special fluoro-containing copolymerized unit with a curing site monomer selected from the group consisting of 1,1,3,3,3-pentafluoropropylene and v) 2,3,3,3-tetrafluoropropene Elastomeric compositions are readily curable with polyhydroxy curing systems. The resulting cured article has a combination of excellent alkali fluid resistance, superior tensile properties and compression set resistance. |
