RUBBER MIXTURE FOR TIRES, COMPRISING AN IMPROVED VULCANIZING INGREDIENT

摘要

A tire composition, in particular for pneumatic tires, which has a shore-A hardness (DIN 53 505 and ASTM D2240) of at least 40 ShA and no more than 95 ShA and a glass transition temperature Tg (E" max) (DIN 53 513) of at least -80° C and no more than 0° C at a specific temperature sweep of -80° C to +80° C and at a specific compression of 10 + 0.2 percent at 10 Hz, is characterized by the following composition: - at least one vulcanizable diene rubber selected from among natural rubbers, synthetic polyisoprene rubbers, polyisobutylene rubbers, polybutadiene rubbers, and styrene-butadiene rubbers; 35 to 300 phr of at least one active filler selected from among blacks, silicas, silicon-based fillers, and metal oxides, at least 10 phr of said active fillers having to be blacks, silicas, or a combination thereof; - 0 to 250 phr of other or additional additives; - 0.1·10-3 to 42·10-3 mhr of a vulcanizing ingredient that is cross-linked with a functionality of more than 4; and - 0.1 to 20 phr of at least one vulcanization accelerator.
