composite material, method for preparing a composite material, use of a composite material, and cigarette filter the invention relates to a highly cohesive composite material formed of at least one polymer and at least one composed of mineral oxides, silicoaluminates and activated carbon, said composite material having: - a numerical average particle size of at least 150 ælm, - a pore volume (vd1), consisting of pores with diameters between 3.6 and 1,000 nm at least 0,4 cm3 / g, and a cohesion index cin equal to the ratio (numerical mean particle size after an air pressure stress of 4 bar) / (numerical mean particle size without air pressure tension (o bar)), greater than 0.40. It also refers to a method for preparing composite material. It also relates to the use of this composite material as a liquid carrier, catalyst carrier, additive or for liquid or gas filtration, in particular in cigarette filters. |
