  • Patent number: 5428096
    Abstract: An oil-repellent fluororubber composition obtained by compounding a low-molecular weight tetrafluoroethylene resin with a peroxide crosslinked fluororubber having a Mooney viscosity of 90 or more ML.sub.1+10 (100.degree. C.) or compounding a low-molecular weight tetrafluoroethylene resin and an inorganic filler selected from powders of solid substances, such as iron, nickel, cobalt, iron-cobalt alloy, molybdenum, tungsten, tantalum and tungsten-carbide, having surface energy higher than that of copper with a peroxide crosslinked fluororubber. An oil-repellent fluororubber elastomer having excellent oil repellency and at the same time maintaining original mechanical and physical characteristics sufficiently can be obtained, using easily available materials on the market without any special means of processing and treatment.
