<p>The invention concerns a composition comprising a mixture of polymer material (4) and mineral fillers (5) for obtaining a sealing barrier relative to hydrocarbons. The mixture comprises a predetermined proportion of specific mineral fillers for adsorption of all or part of hydrocarbons seeping through by permeability. The proportion is determined on the basis of the permeability of the polymer material. The invention also concerns its uses for hydrocarbon tanks (fuel, diesel oil, solvents) for example for motor vehicles, or pipes transporting hydrocarbons.</p> |
