| abstract |
The present invention relates to a highly tacky composite material formed of one or more polymers and at least one compound selected from inorganic oxides, silicoaluminates and activated carbons and having: a number median particle size of at least 150 μm, 0.4 cm 3 / g Pore volume (Vd1) consisting of pores of 3.6 to 1000 nm diameter, and above (number median particle size after 4 bar pneumatic stress) / (number media particle size without pneumatic stress) greater than 0.40 Cohesion index equal to the ratio CI N. It also relates to a process for producing the composite material. It also relates to the use of such composite materials as liquid supports, catalyst supports, additives or for liquid or gas filtration, in particular in tobacco filters. |
