| 摘要 |
A fuel impermeable, fuel resistant hose having improved high temperature resistant characteristics sufficient to provide extended service life of the hose in a harsh thermal environment comprising at least one fluoropolymer tubular structure, and a backing layer surrounding the at least one fluoropolymer tubular structure wherein the backing layer comprises at least one high temperature resistant elastomer selected from the group consisting of ethylene-acrylate elastomer, ethyl-vinyl acetate copolymer, acrylic rubber, and blends thereof, said backing layer exhibiting superior high temperature resistance compared to conventional backing layers. The hose optionally contains a reinforcement member around the at least one fluoropolymer tubular structure, and a high temperature-resistant cover over the reinforcement member.
