The invention relates to a sulfur-crosslinkable rubber mixture without aromaticnProcess oils containing at least one diene elastomer, at least finely divided as fillers,nprecipitated silica and soot, plasticizers, at least one silane coupling agent as wellnother conventional additives and a process for their preparation. Furthermore, thenInvention rubber products and tires based on this rubber compound.n n n The rubber mixture contains 5 to 60 phr as plasticizer, at least onenMineral oil plasticizer containing polycyclic aromatic compoundsndetermined with the DMSO extract according to the IP 346 method of less than 3% by weightnbased on the total weight of the mineral oil plasticizer and onenGlass transition temperature below -45 ° C, and at least 1 to 20 phrnof a glyceride and / or a factice, and the weight ratio of finely divided,nprecipitated silica to soot in the rubber mixture is 1: 2 to 20: 1. |
