Abstract

Un dispositivo para tratamiento de gases de escape incluye un alojamiento, una estructura frágil elásticamente montada dentro del alojamiento y una estera de montaje no intumescente dispuesta en un espacio entre el alojamiento y la estructura frágil. La estera de montaje incluye una pluralidad de fibras inorgánicas que han sido sometidas a un tratamiento de superficie para incrementar el desempeno de fuerza de retencion de la estera de montaje. También se describen métodos para elaborar una estera de montaje para un dispositivo de tratamiento de gases de escape y para elaborar un dispositivo para tratamiento de gases de escape que incorporen la estera de montaje.
