The invention relates to a rubber composition, comprising a rubber component that has at least one halobutyl rubber in an amount of 60 to 100 phr, and a filler component that comprises fillers F1 having a 14 C content in the range from 0.20 to 0.45 Bq/g carbon; a carbon content in the range from 60% by weight to 85% by weight; and at their surfaces acidic hydroxy groups; wherein the weighted arithmetic mean of the STSA surface areas of the fillers F1 lies in the range from 40 m2/g to 80 m2/g; the fillers F1 have a volume-based median grain-size distribution Dv(50) in the range from 0.5 µm to 5 µm and a volume-based Dv(97) value in the range from 3 µm to 23 µm; and (i) the filler component contains more than 45 phr of fillers F1; or (ii) the filler component contains more than 25 phr of fillers F1 and additionally one or more carbon blacks F2, wherein the weighted arithmetic mean of the STSA surface areas of the carbon blacks F2 lies in the range from 55 m2/g to 95 m2/g. The invention also relates to a vulcanizable and a vulcanized rubber composition based on the aforementioned rubber composition, to a kit-of-parts for producing the vulcanizable rubber composition and to a method for producing the rubber composition and the vulcanizable rubber composition. The invention further relates to a method for further processing the vulcanizable rubber composition. The invention additionally relates to the use of the aforementioned hydrothermally treated lignin for the production of rubber compositions for inner liners.
