ABSTRACT:
Vulcanizable fluorocarbon elastomer compositions containing a vinylidene fluoride copolymer and a fluoroaliphatic sulfonamide curing agent. A second curing agent selected from organic polyhydroxy compounds or derivatives thereof, and an organo-onium accelerator are also employed. The compositions of this invention can be used to prepare shaped articles that exhibit high tensile strength accompanied by high elongation and a low value of compression set.
