Abstract
Absorbent element for spilled petroleum or its derivatives comprising an oil-absorbent, hydrophobic and oleophilic material, essentially based on polyurethane foam, having a specific weight in the range of 15-30 g/l and delimiting open cells and closed cells, the latter being in a percentage equal to or lower than 10% of the total cells. The invention further relates to an assembly comprising a plurality of such elements and a method for fabricating an oil-absorbent material.
