摘要:
The present invention relates to precipitated silica containing aluminum, which has an adjustable BET/CTAB ratio, a process for its manufacture and its use.
摘要:
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.
摘要:
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.
