    摘要: An exhaust gas treatment device includes a housing, a fragile element disposed within the housing, and a mounting mat disposed between the fragile element and the housing for maintaining the positioning of the fragile element, absorbing mechanical shock, and providing thermal insulation. The mounting mat includes a layer or sheet of inorganic fibers with a portion of the layer having a first basis weight and another portion having a second basis weight that is different from the first basis weight. The mat or a vacuum formed insulating pre-form having a variable basis weight in certain regions may be used as end cone insulation in exhaust gas treatment devices.
