低渗透柔性燃料软管
摘要：
一种柔性软管，该柔性软管具有非氟化橡胶内管、非氟化橡胶外覆盖层、基本上由乙烯含量小于30摩尔％的乙烯-乙烯醇共聚物(EVOH)组成的中间阻隔层，并且优选地织物加强件在所述阻隔层和所述外覆盖层之间。非氟化橡胶连结层可以被包括在阻隔层和加强件之间。对含乙醇的燃料和含甲醇的燃料的渗透性是很低的。
摘要（英）：

A flexible hose having a non-fluorinated rubber inner tube, a non-fluorinated rubber outer cover, an intermediate barrier layer consisting essentially of ethylene- vinyl alcohol copolymer (EVOH) having an ethylene content less than 30 mole %, and preferably a textile reinforcement between said barrier layer and said outer cover. A non-fluorinated rubber tie layer may be included between the barrier and the reinforcement. Permeability to ethanol- and methanol-containing fuels is very low.
