Sulfur-crosslinkable rubber composition containing organic fillers and organosilane

Abstract

The present invention relates to a vulcanizable rubber composition, comprising a vulcanization system VS that comprises at least sulfur and/or at least one sulfur donor, a rubber component K containing at least one rubber that is cross-linkable by means of sulfur, a filler component F that contains at least one organic filler having a 14C content in a range from 0.20 to 0.45 Bq/g of carbon and a BET surface area in a range from >20 to 150 m2/g, and at least one organosilane having at least one hydrolysable group and at least one sulfur atom, to a kit of parts comprising as part (A) a rubber composition containing the above-mentioned components F and K, and as part (B) the vulcanization system VS comprising at least sulfur and/or at least one sulfur donor, wherein the above-mentioned organosilane is contained in part (A), to vulcanized rubber compositions respectively obtainable therefrom, to a use of the above-mentioned products for employment in the fabrication of tires, tire components and rubber articles, and to corresponding tires, tire components and rubber articles as such.
