A rubber blend, particularly for pneumatic vehicle tires, harnesses, straps and hoses. The rubber blend includes at least one rubber blend A of a solid styrene-butadiene rubber with an average molecular weight Mof 100,000 to 5,000,000 g/mol and a liquid butadiene rubber with an average molecular weight Mof 500 to 9000 g/mol, wherein the styrene-butadiene rubber is solution-polymerized or emulsion-polymerized, as well as 30 to 300 phr of at least one silicic acid and further blend components.

Rubber blend with improved rolling resistance behavior

The invention relates to a method for the production of a tire sealant (C) with a polymeric base. A highly viscous first sealant component (A) (including a natural rubber component that is undiluted or diluted with at least one additional natural rubber component and mixture ingredients that are free of a solvent and an activator) is mixed with at least one second sealant component (B) (comprising a separately produced medium with low viscosity containing at least one activator), to combine to the tire sealant (C), wherein a cross linking occurs associated with the subsequent application of the tire sealant (C) to the inside of the tire. Appropriate method steps are disclosed.
