The European Union agreed to support the use of biofuels, its strategic goal is to 2020 common fuel 20% will replace by biological fuel, so as to reduce carbon dioxide (CO2) emissions and fuel dependence on oil. The United States also advocates the use of biofuels, and has made the improve vehicle renewable fuel standard. Using the current main E85 biofuel is biodiesel, ethanol and gasoline by 85% 15% mixture, the degradation products rubber material to have a very strong corroding effect.

Therefore, in addition to high temperature resistant performance besides, fuel hose should have good characteristics of fuel permeability. The fuel hose used rubber materials mainly is LvChun rubber (ECO), acrylic acid rubber (ACM) and HNBR industry (HNBR), these rubber resistant to 150 ¡æ temperature, is displacing buna n (NBR) (cover within) and neoprene (CR) (the sub). Recently, Rachel wong company developed a acrylic rubber NiPOl AR, resistant to high temperature 175 ¡æ. In addition, fluorine rubber has been widely used in automotive fuel hose, but because the price is expensive, fluorine rubber only as a very thin lining, generally for 0.2 ~ 0.7 mm, through out or other methods of additional to the fuel hose in the inside of the cover.

Dupont developed new "advanced polymer structure" (APA) technology, the production of a peroxide sulfide (also called addition cure) special fluorine rubber, can be used in automobile biodiesel hose and turbo charger hose. Dyne-second per square centimeter (Dyneon) company is also the development of a production peroxide vulcanization fluorine rubber new process and its resistance to biodiesel performance than the ordinary fluorine rubber.

Dana and Nero tower-Moore company USES two formic acid glycol esters were together (PEN) production in fuel and fuel conveyor system with hose, this is a kind of multi-layer structure hose, nylon 12 and adhesive lining of the PEN interface layer and adhesive layer, layer and nylon 12 coated with a layer, permeability, electrostatic discharge, in weight and cost aspects are better than the fluorine rubber multilayer hose.
