Mounting mat for mounting an exhaust gas catalytic converter

摘要

A bedding mat for supporting an exhaust gas catalyst in a metallic catalyst housing used to purify motor vehicle exhaust gases comprises a yarn processed to form a flat textile structure. The yarn comprises a plurality of voluminous, thermally stable filaments which are aligned parallel with each other in a bundle and a casing around the bundle which decomposes upon heating. An edge protection made of thermally stable threads is provided along the edges of the flat structure.
