Abstract
A pollution control device has a metal housing, a solid pollution control device disposed within the metal housing, and a mounting mat disposed between the pollution control element and the housing for positioning the pollution control element and for absorbing mechanical and thermal shock. The mounting mat includes a layer of intumescent material having at least one insert formed of a resilient, flexible, fibrous non-intumescent material. The insert is positioned along at least a portion of at least one lateral edge of the mounting mat to prevent erosion of the intumescent material and to provide a seal between the pollution control element and the housing.
