SULPHUR-CROSSLINKABLE RUBBERIZING MIXTURE

摘要

The invention relates to a sulphur-crosslinkable rubberizing mixture for strengthening elements in motor vehicle pneumatic tyres, comprising 70 to 100 phr (parts by weight, based on 100 parts by weight of total rubbers in the mixture) of natural rubber, up to 30 phr of at least one polybutadiene, 40 to 70 phr of at least one carbon black and a bonding system. The invention further relates to motor vehicle pneumatic tyres comprising sulphur-crosslinked rubberizing mixture. The key conflict between tear propagation resistance, stiffness and heat build-up is solved by virtue of the carbon black being a nanostructured carbon black with rough surface.
