Abstract
A curable fluoroelastomer composition comprising at least one fluoroelastomer, a bisphenol curative, and a peroxide curative provides a non-post cure fluoroelastomer material suitable for use in the manufacture of, for example. When cured (vulcanized), the composition exhibits an improved compression set resistance, in comparison to the fluoroelastomer cured by the bisphenol curative alone, without performing a post-cure procedure or with only performing a limited or reduced post-cure procedure of up to 2 hours, preferably not more than 1 hour (for example, 1–30 min.) at 175° C.–235° C. (e.g., 350° F.–450° F.).
