Refrigerant-transporting hose

Abstract

A refrigerant-transporting hose including an inner tube, an outer tube, and a reinforcing layer between the inner tube and the outer tube, the outer tube being formed of an outer tube rubber composition, the outer tube rubber composition containing a brominated copolymer rubber obtained by brominating a copolymer rubber of isomonoolefin and p-alkylstyrene, the content of the repeating units having bromine constituting the brominated copolymer rubber being from 0.8 to 1.5 mol % with respect to the total amount of the repeating units constituting the brominated copolymer rubber, a carbon black A having a dibutyl phthalate absorption amount of 40 cm3/100 g or less, a brominated alkylphenol resin, and zinc oxide, the content of the carbon black A being 35 parts by mass or greater with respect to 100 parts by mass of the brominated copolymer rubber. Such refrigerant-transporting hose achieves both workability and sealing property at an excellent level.
