The invention relates to rubber compounds comprised of at least one rubber that contains double bonds, of rubber gels, of inorganic peroxide additives and, optionally, of additional fillers and rubber auxiliary agents. The inventive rubber compounds are characterized by a good processability (compound viscosity ML 1+4/100 ~C < 60 ME) when in an uncross-linked state, by improved mechanical properties when in a vulcanized state, especially with regard to the product of the modulus at 100 % elongation and the elongation at break (S100 x D), and by improved tensile strengths. In addition, the vulcanizates produced from the inventive rubber compounds has a lower density, which has an advantageous effect on the weight of the rubber bodies made from the rubber compounds. The vulcanizates are suited for producing conventional rubber articles and for tire component parts.

L'invention concerne des mélanges de caoutchouc contenant au moins un caoutchouc comprenant des doubles liaisons, des gels de caoutchouc et des additifs de peroxydes inorganiques, et éventuellement d'autres charges et adjuvants de caoutchouc. Les mélanges de caoutchouc obtenus selon l'invention se caractérisent, à l'état non réticulé, par une bonne faculté de mise en oeuvre (viscosité du mélange ML 1+4/100 ·C < 60 ME) et, à l'état vulcanisé, par des propriétés mécaniques améliorées, en particulier en ce qui concerne le produit de la contrainte de traction pour un allongement de 100 % et de l'allongement à la rupture (S100 x D), ainsi que par une résistance accrue à la traction. Par ailleurs, les vulcanisats produits à partir des mélanges de caoutchouc selon l'invention présentent une densité réduite, ce qui se répercute de façon avantageuse sur le poids des corps en caoutchouc fabriqués à partir de ces mélanges de caoutchouc. Ces vulcanisats sont adaptés pour la fabrication d'articles techniques en caoutchouc et pour des composants de pneus.
