Abstract:
A curable elastomer composition consisting essentially of:(a) a recycle component of an at least partially vulcanized fluorinated elastomer; and optionally, an unvulcanized fluoroelastomer gum, and(b) an amount of a cure-enhancing additive system that is effective to improve the maximum torque during cure of a composition according to this claim over the maximum torque during cure of a similar composition that does not have the additive system, the additive system consisting essentially of(i) a cure enhancing additive selected from the group consisting of a fluoroaliphatic sulfonamide, a free radical scavenger, and a mixture of the two,(ii) optionally a crosslinking agent for a fluoroelastomer gum, and,(iii) optionally an accelerator.
