Abstract: A melt-blown web contains melt-blown fibers obtained by a) melt-mixing a propylene-based polymer, a first peroxide and a second peroxide at temperatures between 180° C. and 240° C., preferably between 200° C. and 220° C., wherein the first peroxide has a half-life time of 1 hour at a first temperature T1/2 1 and the second peroxide has a half-life time of 1 hour at a second temperature T1/2 2, wherein T1/2 2 is higher than T1/2 1 and b) processing the composition obtained by step a) by a melt-blown process at temperatures between 240° C. and 300° C., preferably between 245° C. and 280° C., to provide the melt-blown fibers.
