Abstract
This invention relates to vulcanizable diene rubber compounds with a high capacity for the addition of sulfur to be varied while processing safety is maintained, for the production of improved rubber moldings, particularly tire components.
Claims11
A vulcanizable rubber compound based on diene rubbers and customary additives, comprising a vulcanizing system contained in the compound comprising
- a) 0.5 to 3.8 parts by weight of compound (I)
- R2N—(C═S)—S—S—(CH2)x—S—S—(C═S)—NR2 (I)
- wherein R=(C6H5CH2);
- and X=6;
- b) 0.5 to 2 parts by weight sulfur;
- and
- c) 0.5 to 3.0 parts by weight of at least one vulcanization accelerator wherein the parts by weight are given in each case with respect to 100 parts by weight of rubber.
