The present invention relates to granular functionalized silicas, wherein The inventive granular functionalized silicas can be used as a support material, especially as a support for enzymes.

Granular functionalized silica, process for preparation thereof and use thereof

The present invention relates to novel granular silicas for use as support material, especially as support for catalysts for fixed bed reactors, and to the production and use thereof.

Coarse support silica particles

The present invention relates to storage-stable product systems having high latency and good mechanical stability, which are suitable, inter alia, for premix formulations. Furthermore, the present invention relates to a method for producing the formulations according to the invention and the use thereof.

Storage-stable product systems for premix formulations

The present invention relates to novel precipitated silicic acids for use as support materials, manufacture thereof and use thereof.

Precipitated silicic acids for support applications
