The present invention provides a multilayer mounting mat for mounting a pollution control element. The mounting mat comprises a layer of intumescent material between two non-intumescent layers defining opposite major sides of the mounting mat. The mounting mat in accordance with the present invention is suitable for mounting a pollution control element in a pollution control device and is in particular suitable for mounting fragile monolith such as thin-wall and ultra thin-wall monoliths. Also, the mounting mats conveniently exhibit a good or excellent holding pressure over a wide temperature range and can be formulated in an inexpensive way. The invention also provides a pollution control device comprising a pollution control element arranged in a casing with the mounting mat disposed between the casing and pollution control element.
La présente invention concerne une latte de montage multicouche permettant de monter un élément de lutte contre la pollution. La latte de montage comporte une couche de matière intumescente entre deux couches non intumescentes définissant des côtés principaux opposés de la latte de montage. Celle-ci se prête au montage d'un élément de lutte contre la pollution dans un dispositif de lutte contre la pollution et est spécialement conçue pour monter un monolithe fragile, notamment des monolithes à parois fine et ultrafine. Les lattes de montage font preuve d'une pression de maintien bonne ou excellente sur une large fourchette des températures et peuvent être formulées de manière plus coûteuse. L'invention concerne également un dispositif de lutte contre la pollution comprenant un élément de lutte contre la pollution disposée dans un boîtier, la latte de montage venant entre le boîtier et l'élément de lutte contre la pollution.
