Rubber composition useful e.g. for manufacturing tires, comprises e.g. a solution polymerized styrene butadiene rubber and/or emulsion polymerized styrene butadiene rubber, a polar resin and further additives

摘要

Rubber composition comprises at least one solution polymerized styrene butadiene rubber and/or one emulsion polymerized styrene butadiene rubber (80-100 phr), at least one silicic acid (50-300 phr) with cetyl trimethyl ammonium bromide (CTAB) surface area according to ASTM D 3765of 150-400 m 2>/g, at least one polar resin (5-50 phr), bis(triethoxysilylpropyl)disulfide (TESPD) and/or bis(triethoxysilylpropyl)tetrasulfide (TESPT)(0.1-12 phf) and further additives. Rubber composition comprises at least one solution polymerized styrene butadiene rubber and/or one emulsion polymerized styrene butadiene rubber (80-100 phr), at least one silicic acid (50-300 phr) with cetyl trimethyl ammonium bromide (CTAB) surface area according to ASTM D 3765of 150-400 m 2>/g, at least one polar resin (5-50 phr), bis(triethoxysilylpropyl)disulfide (TESPD) and/or bis(triethoxysilylpropyl)tetrasulfide (TESPT)(0.1-12 phf), where the proportion of TESPD and/or TESPT is 0.1- 4 phf by weight, when silicic acid (50-100 phr) is present with a CTAB surface area according to ASTM D 3765150-400 m 2>/g, and where the proportion of TESPD and/or TESPT is 4-12 phf, when silicic acid (100-300 phr) is present with a CTAB surface area according to ASTM D 3765of 150-400 m 2>/g and further additives.
