Abstract:
Compositions of fluoroelastomers containing copolymerized units of tetrafluoroethylene, propylene, a first cure site selected from the group consisting of i) trifluoroethylene, ii) 3,3,3-trifluoropropene-1, iii) 1,2,3,3,3-pentafluoropropylene, iv) 1,1,3,3,3-pentafluoropropylene, and v) 2,3,3,3-tetrafluoropropene, and a second cure site selected from the group consisting of i) copolymerized units of a brominated cure site monomer, ii) copolymerized units of an iodinated cure site monomer, iii) copolymerized units of a chlorinated cure site monomer, iv) brominated endgroups, v) iodinated endgroups and vi) a combination of any of i) - v) are readily curable with polyhydroxy curing systems. The resulting cured articles have a combination of excellent resistance to alkaline fluids, superior tensile properties and compression set resistance, and excellent adhesion to metal substrates. Optionally, the fluoroelastomers may be dual cured by both a polyhydroxy system and an organic peroxide system.
