A holding material (2) for mounting a pollution control element (1) in a pollution control apparatus (10) that provides for a high friction coefficient with the casing (4) and/or the pollution control element and can hold the pollution control element with good stability. The holding material comprises a fiber material (e.g., in the form of a mat) having a thickness and being provided with a friction layer (3) comprising inorganic colloidal particles (5) on an outer peripheral surface and/or an inner peripheral surface of the fiber material.
L'invention porte sur un matériau de retenue (2) permettant de fixer un élément antipollution (1) dans un appareil antipollution (10) et ayant un coefficient de friction élevé avec l'enveloppe (4) et/ou l'élément antipollution, ce matériau de retenue pouvant maintenir l'élément antipollution à une bonne stabilité. Le matériau de retenue comprend un matériau fibreux (se présentant sous la forme d'un tapis) d'une certaine épaisseur et pourvu d'une couche de friction (3) comprenant des particules colloïdales inorganiques (5) sur une surface périphérique externe et/ou sur une surface périphérique interne.
