The present invention relates to a process for producing a rubber compound with improved mechanical properties. In particular, the rubber blends have increased fracture ductility, tensile strength and / or tear strength while decreasing permanent strain (DVR). The rubber blend is a rubber (A) having at least two functional groups which can be crosslinked by hydrosilylation, a hydrosiloxane or hydrosiloxane derivative comprising on average two or more SiH groups per molecule as a crosslinking agent (B) Or a mixture of a plurality of hydrosiloxanes or a mixture of a plurality of hydrosiloxane derivatives, a hydrosilylation catalyst system (C), at least one filler (D) and a crosslinking accelerator (E) which can be crosslinked by a hydrogensilification reaction. do. |
