摘要： A perfluoroelastomer composition comprises a perfluoroelastomer (e.g., tetrafluoroethylene/perfluoro(methyl vinyl ether) copolymer), an organic peroxide (e.g., 2,5-dimethyl-2,5-di(tert-butylperoxy)hexane and a scorch retarder (e.g., o-phenylphenol), and the perfluoroelastomer composition is excellent in processability and unlikely to scorch. Furthermore, a perfluoro rubber molded article obtained by thermal crosslinking of the perfluoroelastomer composition is excellent in rubber physical properties such as tensile strength and elongation at break and in a compression set property.
