  • Patent number: 7902285
    Abstract: Sulfur-vulcanizable rubber mixture without aromatic process oils, in particular for the tread rubber of vehicle pneumatic tires, containing at least one diene rubber, carbon black, mineral oil plasticizer, and resin. A vehicle pneumatic tire with a tread rubber that is composed at least partially of a rubber mixture of this type vulcanized with sulfur is also disclosed.
    Type: Grant
    Filed: January 12, 2007

  • Patent number: 7411018
    Abstract: The invention relates to a sulfur-vulcanizable rubber compound, in particular for treads of tires, which contains at least one diene rubber, liquid polybutadiene with a molecular weight of 1500-10000 g/mol and a vinyl content of 15-50%, at least one polar filler, at least one high-structure black with an iodine adsorption number of 115-200 g/kg and a DBP number of 125-160 mL/100 g and at least one glyceride and/or one factice for good abrasion characteristics, good wet traction and good traction on ice and snow with good dry braking at the same time.

  • Patent number: 6822043
    Abstract: Sulfur vulcanizable rubber composition which does not contain aromatic process oils including at least one diene elastomer, at least finely dispersed, precipitated silica and carbon as fillers, softeners, at least one silane coupling agent, and additional common additives as well as a process for their production. Additionally, the invention relates to rubber products and tires made based on such rubber compositions. The rubber composition can comprise 5 to 60 phr of at least one mineral oil softener as a softener, with a content of polycyclic aromatic compositions of less than 3 wt-% in relation to the total weight of the mineral oil softener, determined by the DMSO extract according to the IP 346 method, and a glass transition temperature below −45° C., and 1 to 20 phr of at least one glyceride and/or of a factice, and the weight ratio of finely dispersed, precipitated silica to carbon black being 1:2 to 20:1 in the rubber composition.
