REFRIGERANT-TRANSPORTING HOSE

摘要

Disclosed is a refrigerant-transporting hose involving an inner tube layer composed of a gas barrier layer and a rubber layer adjacent to the outer surface of the gas barrier layer, wherein the rubber layer is composed of a rubber composition comprising 100 parts by mass of a raw material rubber, 1 to 15 parts by mass of an alkylphenol formaldehyde resin and 1 to 8 parts by mass of hydrotalcite, the raw material rubber comprises at least one component selected from the group consisting of BIMS and a copolymer rubber that is a butyl rubber and/or a halogenated butyl rubber, and the gas barrier layer is composed of a polyamide resin composition containing a modified polyamide which is produced by blending a polyamide with a modified polyolefin containing a carboxyl group. In the refrigerant-transporting hose, the adhesion between the gas barrier layer and the rubber layer is excellent.
