Abstract
A resin composition for a refrigerant-transporting hose, including: a semi-aromatic polyamide resin (A) as a main component; an aliphatic polyamide resin (B); and an elastomer (C), in which the aliphatic polyamide resin (B) is dispersed in a phase formed of the semi-aromatic polyamide resin (A) and the elastomer (C), which is not crosslinked, is incorporated in the form of particles into the dispersed aliphatic polyamide resin (B). Thus, excellent refrigerant permeation resistance and acid resistance, and at the same time, for example, extrusion processability and flexibility, are obtained.
