  • Patent number: 8735485
    Abstract: The invention relates to a rubber mixture, in particular for pneumatic vehicle tires, more particularly for the inner liner of a pneumatic vehicle tire, seat belts, belts and hoses. The rubber mixture is characterized by the following composition: 30 to 100 phr of at least one halobutyl rubber, 0 to 70 phr of at least one other diene rubber, 5 to 100 phr of at least one dry mixture compound containing at least 25% of at least one delaminated aluminohydrosilicate modification, the delaminated aluminohydrosilicate modification having a two-layer grid, 10 to 100 phr of at least one carbon black with an STSA surface as defined according to ASTM-D 6556 of from 10 to 60 m2/g and a DBP number defined according to ASTM-D 2414 of from 50 to 160 mL/100g, 3 to 20 phr of at least one mineral-oil softener, and other additives.

  • Publication number: 20090054551
    Abstract: The invention relates to a rubber mixture that can be cross-linked by sulphur and contains, in order to achieve low-temperature flexibility and high-temperature rigidity, at least one diene rubber, between 5 and 150 phr (weight parts in relation to 100 weight parts of the total rubber mass) of at least one type of soot with an iodine adsorption index >65 g/kg and a DBP index >90 cm3/100 g, and between and 150 phr of a type RAE (residual aromatic extract) crude oil fraction as a softener. The weight ratio of the soot to the crude oil fraction in the mixture is 1:1 to 1:10.
