LOW SHEAR MOUNTING MAT FOR POLLUTION CONTROL DEVICES

摘要

A mounting mat (20) for an exhaust gas treatment device (10) including high temperature resistant ceramic fibers containing alumina and/or high temperature resistant biosoluble inorganic fibers, organic binder which at least partially liquefies at elevated temperature prior to binder burnout, colloidal inorganic oxide and optionally intumescent material. The exhaust gas treatment device (10) includes a housing (12), a fragile catalyst support structure (18) resiliently mounted within the housing (12), and the mounting mat (20) disposed in a gap between the housing (12) and the fragile catalyst support structure (18).
