HOSE FOR TRANSPORTING REFRIGERANT

摘要

An object of the present invention is to provide a hose for transporting refrigerant having superior adhesive strength between a gas barrier layer and a rubber layer. A hose for transporting refrigerant of the present invention comprises an inner tube layer including a gas barrier layer and a rubber layer adjacent to an outer surface of the gas barrier layer. The gas barrier layer comprises a polyamide resin composition comprising from 0.5 to 20 parts by mass of a hydrotalcite per 100 parts by mass of a modified polyamide obtained by blending a polyamide and a carboxyl group-containing modified polyolefin. The rubber layer comprises 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. The raw rubber comprises at least one selected from the group consisting of a BIMS and a butyl rubber and/or a halogenated butyl rubber, which is a copolymer rubber.
