Abstract
A resin material, in which the elongation at break in an environmental condition at a predetermined temperature of 100° C. or higher and 150° C. or lower is 50% or more, a content of a plasticizer is 3 mass % or less with respect to the total mass of the resin material, a strength at break in the environmental condition at this predetermined temperature is 5 MPa or more, the elongation at break is 500% or less, and a 10% modulus is 3 MPa or less, is formed into a tubular form and used as an inner surface layer, an intermediate layer, and an outer surface layer of a hose, and components of an air conditioner are connected through the hose. Such resin material, and also a hose including the resin material, which are mainly used for an air conditioner installed in a vehicle, have improved durability in a high temperature environment.
