Abstract

Provided are non-woven fibrous webs, methods and assemblies thereof. The non-woven fibrous web comprises a plurality of melt-blown fibers. The plurality of melt-blown fibers include a thermoplastic polymer blended with a phosphinate and/or polymeric phosphonate. The provided non-woven articles can afford a fine fiber diameter for enhanced acoustic insulation properties, dimensional stability, and superior flame-retardant properties when compared with conventional non-woven articles having similar fiber diameters.
