摘要： Adding silica particles having specified collective characteristics to a fluororubber formulation enhances direct adhesion between the fluororubber formulation and a copolymer upon curing. Specifically, as measured before being mixed into the fluororubber formulation, the silica particles have an average value of the product “(particle size)×(circularity)” that is 17.5 nm or higher and 500 μm or lower. The silica particles may also have an average particle size of between 25.0 nm inclusive and 500 μm inclusive, and an average circularity of 0.80 or higher. Alternatively, as measured after being incorporated into the fluororubber formulation and then cured, the silica particles have an apparent average value of the product “(particle size)×(circularity)” that is 32.0 nm or higher and 500 μm or lower. The silica particles may also have an apparent average particle size of between 40.0 nm inclusive and 500 μm inclusive as measured after being incorporated into the fluororubber formulation and then cured.

摘要： The invention provides a laminate in which a fluororesin layer and a rubber layer are firmly bonded to each other and the fluororesin layer has low fuel permeability and is less likely to suffer solvent cracking. The laminate includes a rubber layer (A) and a fluororesin layer (B). The fluororesin layer (B) contains a copolymer containing a chlorotrifluoroethylene unit, a tetrafluoroethylene unit, and a perfluoroalkyl vinyl ether unit. The copolymer contains 96.0 to 97.4 mol % of the chlorotrifluoroethylene unit and the tetrafluoroethylene unit relative to all the monomer units constituting the copolymer and 2.6 to 4.0 mol % of the perfluoroalkyl vinyl ether unit relative to all the monomer units constituting the copolymer.
