The present invention relates to a rubber composition having properties of various rubbers and having improved mechanical properties especially with respect to permanent set (DVR), fracture ductility, tensile strength and / or gas permeability for a single compound, Sulfur-low emissivity elastomer blends having a low temperature resistance and a medium resistance. The elastomeric blend may further comprise at least one rubber (A) having at least two functional groups which can be crosslinked by hydrosilylation, at least one functional group having two or more functional groups which can be cross- Other rubber (B) is also contained. At this time, the rubber (B) is chemically different from the rubber (A). The elastomeric blend may also comprise a mixture of hydrosiloxane or hydrosiloxane derivatives or a plurality of hydrosiloxanes or a plurality of hydrosiloxane derivatives containing at least two SiH groups on average per molecule as cross-linking agent (C) And contains at least one filler (E). |
