  • Patent number: 9969880
    Abstract: It is the aim to indicate a thermoplastic elastomer composition which is characterized by particularly good temperature stability from ?40° C. to +150° C. and a particularly good oil resistance, with particularly good physical properties, in particular with a high elongation at break, and which is suitable for use in moldings, injection moldings, extrudates and/or blow moldings. In addition, the thermoplastic elastomer composition according to the invention comprises a mixture of acrylate rubber and polyurethane.
    Type: Grant

  • Publication number: 20100137492
    Abstract: The use of a sulphur-free and low-emission elastomer blend which has properties of various rubbers, and the mechanical properties thereof are improved, in particular, in relation to the permanent set (DVR), elongation at rupture, tensile strength and/or gas permeability (permeation) in relation to the individual compounds, and it also has an improved temperature resistance and an improved resistance to media. The elastomer blend includes a rubber having at least two functional groups which can be cross-linked by hydrosilylation, at least one other rubber comprising at least two functional groups which can be cross-linked by hydrosilylation, and can be used as a material in the insertion area of the fuel cells, in particular, the direct-methanol-fuel cells.

  • Patent number: 7714053
    Abstract: A method for producing a rubber compound wherein the mechanical properties thereof are improved. In particular, the rubber compound has an increased elongation at rupture and/or increased tensile strength and/or increased tear strength and also a reduced compression set (DVR). The rubber compound includes a rubber which has at least two functional groups which can be cross-linked by hydrosilylation, a cross-linking agent consisting of hydrosiloxane or a hydrosiloxane derivative or a mixture of several hydrosiloxanes or derivatives, which include at least two SiH-groups per molecule in the center, a hydrosilylation catalyst system, at least one filling material and a coagent which can be cross-linked by hydrosilylation.
