Our special manufacturing process offers significant benefits, such as high chemical purity and selectively adjustable pore volumes. Other features, such as surface properties, bulk densities or water absorption capacity can also be adjusted to your requirements. Choose from our wide range of micronised silicas or let us know your requirements. We will be happy to find the right solution for your specific application. KÖSTROPUR® / KÖSTROSORB® To find perhaps the ideal product that suits your application you have two options. You can use the filter or the table below, to search directly for your application.

A 6-digit numerical code is normally added to the Köstropur® trade name as follows: The first pair of digits give the (residual) water content in the product (in %). The second pair of digits represents the average particle size (in µm). The third pair of digits provides information about the specific pore volume (in (cc/g)*10). The 4-digit code for our Köstrosorb® products refers to the first two properties mentioned: Water content (in %) and average particle size (in µm).
