Abstract

Die Erfindung betrifft einen mit Abgaskatalysator ausge­ rüsteten Auspuff mit Wärmedämmung, wobei die Wärmedämmung aus einem Formkörper aus verdichtetem, mikroporösem Wärme­ dämmaterial besteht, der zur Formstabilisierung mindestens einseitig kaschiert ist oder mit 0,1 - 5 Gew.-% Härter ver­ sehen ist. The invention relates to a catalytic converter with exhaust equipped exhaust with thermal insulation, the thermal insulation from a molded body made of compressed, microporous heat Insulation material exists that at least for shape stabilization is laminated on one side or ver with 0.1 - 5 wt .-% hardener see is.
