Thermoplastic resin composition for refrigerant transport hose, and refrigerant transport hose

Abstract

To provide a refrigerant transport hose that exhibits excellent flexibility, resistance to refrigerant permeation, and resistance to deterioration.SOLUTION: A thermoplastic resin composition for a refrigerant transport hose has a sea-island structure in which an elastomer is present as a domain in a matrix including a thermoplastic resin, the thermoplastic resin composition comprising 100 pts.mass of an elastomer, 30-100 pts.mass of a thermoplastic resin, and 0.5-10 pts.mass of a hydrotalcite and / or a magnesium-aluminum solid solution, wherein the thermoplastic resin includes 50-100 pts.mass of a polyamide on the basis of 100 pts.mass of the thermoplastic resin, and the elastomer includes an elastomer having a polyisobutylene skeleton.SELECTED DRAWING: Figure 1
