EXHAUST GAS TREATMENT DEVICE AND METHOD FOR MAKING THE SAME

摘要

A device for treatment of exhaust gases includes a housing (12), a fragile structure (18) resiliently mounted within the housing (12), and a non-intumescent mounting mat (20) disposed in a gap between the housing (12) and the fragile structure (12). The mounting mat (20) includes a plurality of inorganic fibers that have undergone a surface treatment to increase the holding force performance of the mounting mat (20). Also disclosed are methods of making a mounting mat (20) for an exhaust gas treatment device and for making an exhaust gas treatment device incorporating the mounting mat (20).
