Rubber composition usable for the manufacture of tires, comprising at least: i) a diene elastomer; ii) a white charge as reinforcing filler and iii) a coupling agent (filler white / elastomer), characterized in that said white filler is consisting in whole or in part of a titanium oxide having the characteristics following: a) its BET specific surface is between 20 and 200 m2 / g; b) its average particle size (in mass), denoted dw, is between 20 and 400 nm; c) its disagglomeration speed, noted .alpha., measured in the so-called test ultrasonic deagglomeration, at 100% power of an ultrasonic probe 600 W, is greater than 2.10-2 µm-1 / s. Use of a composition of rubber according to the invention for the manufacture of articles made of rubber, in particular tires or semi-finished products made of rubber intended for these tires. The composition of the invention is particularly intended for the manufacture of colored tires or colored semi-finished articles such as treads or sidewalls tires. |
