A hose capable of exhibiting heat resistance and oil resistance at a high temperature exceeding 150 ° C. is provided. A hose comprises a raw material composition containing the following component (A), component (B), component (C) and component (D) in an amount of 0.05 to 5 per 100 parts by mass of the component (A). It is formed from a thermoplastic elastomer composition obtained by dynamic crosslinking with a mass part of a crosslinking agent. Component (A): 50 to 85 parts by mass of acrylic rubber per 100 parts by mass in total of component (A) and component (B). Component (B): 15 to 50 parts by mass of the thermoplastic polyester resin per 100 parts by mass in total of component (A) and component (B). Component (C): A graft copolymer composed of an olefin polymer segment and a vinyl copolymer segment, or a precursor thereof, in an amount of 1 to 35 masses per 100 mass parts of component (A) and component (B) in total. Department. Component (D): The plasticizer is 60 parts by mass or less per 100 parts by mass of the component (A). [Selection figure] None |
