| description | The disclosure herein includes rapid gas decompression (RGD)-resistant fluoroelastomeric compositions and includes a curable fluoropolymer having a curesite monomer with at least one functional group capable of curing with a peroxide curative. The compositions include a bisphenyl-based curative and an organic peroxide curative and an organic peroxide co-curative. The fluoroelastomeric compositions have a ratio of the bisphenyl-based curative to the organic peroxide co-curative of about 0.25:1 to about 1.5:1 and a ratio of the bisphenyl-based curative to the organic peroxide of about 0.5:1 to about 1.5:1. Such compositions can be formed into seals meeting RGD industry standards in a variety of sizes, up to and/or exceeding 5 mm in thickness or cross-sectional diameter. |
