The present invention relates to highly disperse precipitated silicas which exhibit an extremely high level of reinforcement of rubber vulcanizates, to a process for their preparation, and to their use as filler for rubber mixtures.

Higly dispersible silica for using in rubber

The present invention relates to precipitated silicas which have extremely low microporosity and high rubber activity, to a process for their preparation, and to their use as filler for rubber mixtures.

Specially precipitated silicic acids for rubber applications

The present invention relates to precipitated silicic acids, which have a particularly narrow particle size distribution in combination with a special pore size distribution, to a method for the production thereof, and to the use thereof as a filler for rubber mixtures.

Precipitated silicas as a reinforcing filler for elastomer mixtures

The present invention relates to a highly dispersible silica which has a high surface area, a process to manufacture the aforesaid silica and its use as a tire filler for utility vehicles, motor cycles and high speed vehicles.

Highly dispersible precipitated silica having a high surface area

Precipitated silicas useful, for example, as fillers in elastomer mixtures or vulcanizates have a particularly broad pore size distribution of the pores with a pore diameter smaller than that of the maximum of the derivative of the pore volume distribution function, and have simultaneously very low microporosity and high rubber activity.

Precipitated silicas with particular pore size distribution

Precipitated silicas which have a broad pore size distribution of the pores with a pore diameter smaller than that of the maximum of the derivative of the pore volume distribution function are useful, for example, for tires.
