High quality melt-blown webs having improved barrier properties (3rd drop, cm H2O resp. mbar) and a widened process window. The melt-blown webs show a specific chain structure.

High quality melt-blown webs with improved barrier properties

Melt-blown fiber comprising two polypropylenes which differ in their molecular weight.

Melt blown web with good water barrier properties

Melt-blown webs having a widened process window and better barrier properties (3rd drop, cm H2O resp. mbar). The melt-blown webs are made from so-called 'controlled rheology' propylene (CR-PP), which has been visbroken without the use of peroxide but with a specific type of visbreaking additive.

Melt-blown webs with improved properties

Synergistic visbreaking composition of peroxide and a hydroxylamine ester for increasing the visbreaking efficiency for polypropylene polymers at melt extrusion temperatures below 250&#xb0; C. and its use in visbreaking polypropylene. The present invention is furthermore related to the use of such visbroken polypropylene polymers for producing melt blown non-wovens with improved barrier properties.

Method of forming melt-blown non-wovens

Melt-blown webs having no shots and improved barrier properties, whereby the melt-blown webs are made out of a so-called 'controlled rheology' propylene (CR-PP), which was visbroken without any peroxide.

Melt-blown webs without shots and with improved barrier properties

Heterophasic polyolefin composition with improved optical properties, its preparation, articles made therefrom, particularly films, and use of the heterophasic polyolefin composition.
