| abstract |
The present invention relates to a composite material of high tack strength, formed from one or more polymers and one or more compounds selected from mineral oxides, silicoaluminates and activated carbon, wherein the composite material has:n n n An average particle size of at least 100 μm;n n n A pore volume (Vd1) of at least 0.2 cm 3 / g, formed by a pore diameter of 3.6 to 1000 nm; Andn n n Cohesive strength such that the amount of particles having a size of less than 100 μm, obtained after receiving an air pressure of 2 bar, is less than 1.5% by volume, preferably 0.0% by volume.n n n The present invention also relates to a process for producing the composite material. It also relates to the use of such composite materials, in particular in tobacco filters, as liquid supports, catalyst supports, additives, or for liquid or gas filtration. |
