PROBLEM TO BE SOLVED: To provide the fuel system rubber hose that can fill all the basic performance of fuel permeability, fuel proof performance, ozone resistance and low temperature performance with the non-halogen system material. SOLUTION: It is the fuel system rubber hose to include an inner pipe consisting of the composition that the main material is the blend material (A) with NBR and ACM by a relatively high polymer composition in the fuel permeability and the fuel resistant performance and the blend material (B) with NBR and ACM by a relatively high polymer composition in the resistance ozone performance and the low temperature performance. The desirable blend material (A) is the one that ACM is made of EA or MEA or its mixture as the main material and the desirable blend material (B) is the one that ACM is made of BA as the main material. Also, the desirable composite for the inner pipe is the one that a filler is added with the blend material (A). COPYRIGHT: (C)2006,JPO&NCIPI
