Aerosol-generating article comprising a hollow tubular support element

An aerosol-generating article having an upstream end and a downstream end, the aerosol-generating article defining a longitudinal direction between the upstream end and the downstream end, the aerosol-generating article comprising:

• an aerosol-forming substrate;
• a hollow tubular support element disposed downstream of the aerosol-forming substrate and extending along the longitudinal direction, wherein the hollow tubular support element defines an opening extending in the longitudinal direction and configured for aerosol to flow towards the downstream end,
• a filter disposed downstream of the hollow tubular support element in the longitudinal direction,
• wherein a hardness of the aerosol-generating article at the hollow tubular support element is at least about 80%;
• and
• wherein the hardness of the aerosol-generating article at the hollow tubular support element is determined by means of the DD60A Test.
