Abstract
A hose for transportation of refrigerant includes an inner layer, a reinforcing layer, and an outer layer. The inner and outer layers each include a thermoplastic resin composition having a sea-island structure including a matrix containing a thermoplastic resin and a domain containing an elastomer. A water vapor permeability coefficient of the thermoplastic resin composition of the outer layer at a temperature of 60° C. and a relative humidity of 100% is 10.0 g·mm/(m·24 h) or less. An oxygen permeability coefficient of the thermoplastic resin composition of the inner layer at a temperature of 21° C. and a relative humidity of 50% is 0.05 cmmm/(m·day·mmHg) or less. A water vapor permeation amount of the hose is 6.0 mg/(240 h·cm) or less. A hydrofluoroolefin HFO-1234permeation amount of the hose is 170 g/(m·72 h) or less, and the mass per 1 mof the outer surface area of the hose is 3000 g/mor less.
