Abstract: Hoses include a tube, a reinforcement layer disposed outwardly from the tube, and a cover layer disposed outwardly from the reinforcement layer. The cover layer may be based on a first elastomeric blend of a first chlorinated polyethylene and chlorosulphonated polyethylene, a first flame-resistant composition, and a peroxide/sulfur curing system. The tube may be based upon a second elastomeric blend of a second chlorinated polyethylene and ethylene vinyl acetate rubber, a second flame-resistant composition, and a peroxide curing system. The first flame-resistant package and the second flame-resistant package includes one or more ingredients selected from the group consisting of antimony oxide, zinc molybdate/magnesium silicate complex, magnesium aluminum hydroxy carbonate, and aluminum trihydroxide. In some aspects, the hoses meet the testing performance requirements of EN 45545-2, HL2/R22 category standard, and EN854 type 2TE standard.

Abstract: A hose includes an inner tube defining a central longitudinal axis there through, and is formed of a vulcanized rubber and a plurality of rod shaped particles orientated substantially parallel with the central longitudinal axis, along with other typical materials. The inner tube has a tube wall thickness (t) of between about 0.5 mm to about 1.5 mm, and the plurality of rod shaped particles is incorporated in an amount of 10% or less by weight. The hose further includes a tie layer directly surrounding the inner tube, a first reinforcement layer surrounding the tie layer, and at least a second reinforcement layer surrounding the first reinforcement layer. An interlayer is interposed between the first and the second reinforcement layer, and the interlayer bonds the first reinforcement layer to the second reinforcement layer. An outside cover surrounds the second reinforcement layer, as well as any additional layers.

Abstract: A hose includes a fluorothermoplastic or thermoplastic polyester elastomer tube layer, a nitrile rubber friction layer disposed over the tube layer, a reinforcement layer disposed over the friction layer, the reinforcement layer comprising braided steel wire, and a cover layer disposed over the reinforcing layer, where the cover layer may comprise chlorinated polyethylene. The tube layer defines a lumen in the hose, and a vapor return line is disposed within the lumen of the hose, where the vapor return line may be based upon thermoplastic polyester elastomer. Hose embodiments of the disclosure may be useful in fueling applications for vehicles using fuels such as gasoline, gasohol, diesel, biodiesel, avgas or jet fuel.
