Peroxide curable fluoropolymer compositions containing solvents and methods of use thereof

摘要

A curable composition comprising 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 weight percent to 97.5 weight percent based on the weight of the curable composition, and the solvent is from 1 weight percent to 39 weight percent based on the weight of the curable composition. Exists. The absolute value obtained by subtracting the second solubility parameter from the first solubility parameter is 8.2 (MPa) 1/2 or less. The solvent may have a solubility parameter in the range of 9.6 (MPa) 1/2 to 26 (MPa) 1/2. Also disclosed is a method of making a cured fluoroelastomer from a curable composition.
