Abstract

A method for producing a heat-resistant crosslinked fluorocarbon rubber formed body, comprising: (a) a step of melt-kneadingtopart by mass of an organic peroxide,toparts by mass of an inorganic filler, and more thanparts by mass andparts by mass or less of a silane coupling agent, with respect toparts by mass of a base rubber containing a fluorocarbon rubber, at a temperature equal to or higher than a decomposition temperature of the organic peroxide, to prepare a silane master batch; a heat-resistant crosslinked fluorocarbon rubber formed body obtained by the method, a silane master batch, a mixture and a formed body thereof, and a heat-resistant product.
