Beschreibung
Zusammenfassung:	A fibrous structure including one or more nonwoven material layers comprising a fiber matrix, where the fiber matrix comprises polymeric binder fibers having a softening and/or melting temperature of about 190 ºC or greater, where the article is adapted to withstand temperatures of about 190 °C or greater while in use; and where the article is a thermoacoustic insulation material. L'invention concerne une structure fibreuse comprenant une ou plusieurs couches de matériau non tissé comprenant une matrice de fibres, la matrice de fibres comprenant des fibres de liant polymère présentant une température de ramollissement et/ou de fusion supérieure ou égale à environ 190 °C, l'article étant conçu pour résister à des températures supérieures ou égales à environ 190 °C lors de l'utilisation ; et l'article consistant en un matériau d'isolation thermoacoustique.
