Beschreibung
Zusammenfassung:	A curable composition that includes an amorphous, peroxide-curable fluoropolymer having a first solubility parameter, a solvent having a second solubility parameter, and a peroxide. The amorphous, peroxide-curable fluoropolymer is present from 60 percent to 97.5 percent by weight versus the weight of the curable composition, and the solvent is present from 1 percent to 39 percent by weight versus the weight of the curable composition. The absolute value of the first solubility parameter minus the second solubility parameter is less than or equal to 8.2 (MPa)1/2. The solvent may have a solubility parameter in a range from 9.6 (MPa)1/2 to 26 (MPa)1/2. Methods of making a cured fluoroelastomer from the curable composition are also disclosed.
