    Abstract: 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.

    Abstract: The present invention provides a flexible pipe having excellent blister resistance in a high-temperature and high-pressure environment even though including a thick resin pipe. The flexible pipe includes a resin pipe having a thickness of greater than 5 mm. The resin pipe is formed from a resin having a CO2 permeability coefficient P(CO2) of 20×10−9 cm3·cm/cm2·s·cmHg or lower at 150° C., a CH4 permeability coefficient P(CH4) of 10×10−9 cm3·cm/cm2·s·cmHg or lower at 150° C., a ratio D(CO2)/S(CO2) between a CO2 diffusion coefficient D(CO2) and a CO2 solubility coefficient S(CO2) of 3×10−5 Pa·m2/s or higher at 150° C., and a ratio D(CH4)/S(CH4) between a CH4 diffusion coefficient D(CH4) and a CH4 solubility coefficient S(CH4) of higher than 15×10−5 Pa·m2/s at 150° C.
