HOSE FOR TRANSPORTING REFRIGERANT

摘要

Disclosed is a hose for transporting refrigerant with excellent adhesion between a gas-barrier layer and a rubber layer. The hose for transporting refrigerant includes an inner-tube layer composed of a gas-barrier layer and a rubber layer adjacent to the outer surface thereof, wherein the gas-barrier layer is made of a polyamide resin composition comprising 0.5-20 parts by mass of a hydrotalcite per 100 parts by mass of a modified polyamide obtained by blending a polyamide with a carboxyl group-containing modified polyolefin, and the rubber layer is made of a rubber composition obtained by compounding 1-15 parts by mass of an alkylphenol formaldehyde resin per 100 parts by mass of a raw-material rubber, the raw-material rubber containing at least one selected from a group consisting of a BIMS and a copolymer rubber which is a butyl rubber and/or a halogenated butyl rubber.
