Abstract

The disclosure relates to a multilayered hose (1, 10) with a plurality of coaxially arranged sheaths (2, 3, 4, 5, 6, 7, 8, 12, 13). The multilayered hose (1, 10) includes at least a force bearing sheath (2, 6), a diffusion reducing sheath (4), and an adhesion promoting layer (3, 5) that is arranged between the force bearing sheath (2, 6) and the diffusion reducing sheath (4) and that increases the bonding force between said force bearing sheath (2, 6) and said diffusion reducing sheath (4). The adhesion promoting layer (3, 5) includes a mixture of: 65 to 85 parts of acrylonitrile butadiene rubber, 15 to 35 parts of styrene butadiene rubber, 75 to 125 parts of carbon black N990, 30 to 100 parts of calcium magnesium carbonate, 5 to 15 parts of zinc oxide, 5 to 20 parts of magnesium-aluminium hydroxycarbonate, 25 to 125 parts of resin package blend, 2 to 10 parts of N-(1.3-dimethylbutyl)-N′-phenyl-p-phenylendiamine, 5 to 15 parts of triallyl cyanurate, and 0.5 to 5 parts of a vulcanizing agent.
