<p><P>PROBLEM TO BE SOLVED: To provide a duct structural member excellent in flexibility and heat insulation and also excellent in adhesiveness with aluminum adhesive tape. <P>SOLUTION: This duct structural member formed such that has side chains in molecules among low polar elastomers formed of carbon and hydrogen comprises an outer layer 5 formed mainly of, for example, 1, 2-polybutadiene having an modulus of elasticity of 200 MPa or less by a test method specified in JIS K7171. Accordingly, when the aluminum adhesive tape is wrapped around the outer peripheral surface of the outer layer 5 of a duct hose having excellent flexibility and heat insulation, the aluminum adhesive tape is satisfactorily adhered to the outer layer 5, and the connection thereof with an air conditioning apparatus can be stably maintained for a long period. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
