MOUNTING MAT FOR POLLUTION CONTROL ELEMENTS

Mat (1) for mounting a pollution control element in a housing, comprising inorganic fibre material. At an edge surface (20) of the mat a plurality of fibres (30) are heat fused by laser radiation to form fusion volumes (90). The average number of fusion volumes per square millimetre of the edge surf...

More Information
Summary:Mat (1) for mounting a pollution control element in a housing, comprising inorganic fibre material. At an edge surface (20) of the mat a plurality of fibres (30) are heat fused by laser radiation to form fusion volumes (90). The average number of fusion volumes per square millimetre of the edge surface is at least 100, and at least 80% of the fusion volumes have a projected size of between 10 µm and 100 µm.
