A refrigerant conveying hose which is formed of synthetic resin as a whole, and comprises an inner tube serving as an inner layer, and an outer tube including an intermediate layer provided on an outer peripheral surface of the inner tube, a fiber reinforced layer provided on an outer peripheral surface of the intermediate layer and an outer cover layer. The inner tube is formed by using either of (1) a thermoplastic resin, which is an alloy of polyamide resin and an olefin based elastomer, (2) a thermoplastic resin, which is an alloy of a copolymer of polyamide resin and an olefin based elastomer, (3) a thermoplastic resin, which is an alloy of polyamide resin and an urethane based elastomer, and (4) a thermoplastic resin, which is an alloy of a copolymer of polyamide resin and an urethane based elastomer. The intermediate layer is formed by using a thermoplastic resin, which is an alloy of polypropylene (PP) and isobutylene-isoprene rubber (IIR), an adhesive for bonding of the inner tube and the intermediate layer uses a special resin based adhesive, and the outer tube is formed by using a thermoplastic resin, which is an alloy of polypropylene (PP) and ethylene propylene diene rubber (EPDM). <IMAGE> |
