Abstract:
A hose for transporting refrigerant includes an inner tube layer having a gas barrier layer and a rubber layer adjacent to the outer surface of the gas barrier layer. The gas barrier layer is formed using a thermoplastic resin composition comprising a polyamide resin and a modified rubber having an acid anhydride group or an epoxy group, the modified rubber being obtained by modifying a modified raw rubber having an acid anhydride group or an epoxy group with a hydrogen bond-forming compound having a functional group which reacts with the acid anhydride group or the epoxy group and a functional group which is able to form a hydrogen bond with an amide bond or a hydroxyl group. The rubber layer is formed using a rubber composition comprising from 1 to 15 parts by mass of an alkylphenol-formaldehyde resin per 100 parts by mass of a raw rubber.
