REFRIGERANT TRANSPORTING HOSE, AND POLYAMIDE RESIN COMPOSITION FOR FORMING GAS BARRIER LAYER THEREFOR

摘要

PROBLEM TO BE SOLVED: To provide a refrigerant transporting hose having superior durability by preventing deterioration of a gas barrier layer caused by a refrigerant and a compressor oil in a refrigerant transporting hose having a gas barrier layer comprising a polyamide resin composition.

SOLUTION: This refrigerant transporting hose 1 includes a gas barrier layer 2 comprising a polyamide resin composition containing a polyolefin group elastomer. The polyamide resin composition contains one or two or more kinds of metal compound selected from a group comprising a hydroxide, an oxide and a carbonate of a divalent or trivalent metal in an amount of 1-15 wt.% with respect to the total amount of the metal compound and a polymer component. At least a portion of the polyolefin group elastomer is acid-modified.
