PURPOSE:To obtain a fuel hose having high resistance to fuel oil at high temperature, at a low cost, by using a composition composed of polyvinyl chloride and specific amounts of specific polyurethane and polymeric plasticizer as a material to form the surface contacting with fuel oil. CONSTITUTION:100pts.(wt.) of a soft polyvinyl chloride having a polymerization degree of 600-2,500 is compounded with (A) 2-80pts., preferably 15-40pts. of a polyether polyurethane and (B) 4-100pts., preferably 20-50pts. of a polyester-type polymeric plasticizer having a molecular weight of 500-10,000 and obtained by the reaction of a dibasic acid and a low molecular weight diol. |
