<p>A perfluoroelastomer composition for use in vulcanization, comprising a curable perfluoroelastomer polymer and a fluorochemical solvent (preferably selected from perfluorocarbons, perfluoroamines, perfluoromonoethers and hydrofluoromonoethers) having a boiling point of 50 to 280 °C, is provided. The fluorochemical solvent included in the perfluoroelastomer composition may be volatilized while the composition is molded and will not remain in a final molded perfluoroelastomer product. This allows one to provide a perfluoroelastomer product that has reduced emission of ingredients (such as outgas or bleed) therefrom, even when used in harsh environments such as semiconductor processing environments. This composition also provides good workability in the mixing step, and good flowability and moldability in the molding step.</p> |
