Hoffmann Mineral is a manufacturer of Neuburg Siliceous Earth, a natural combination of corpuscular Neuburg Silica and lamellar kaolinite: a loose mixture impossible to separate by physical methods. As a result of natural aging, the silica portion exhibits a round grain shape and consists of aggregated primary particles of about 200 nm diameter. Such a unique structure is responsible for a relatively high specific surface area and oil absorption, which result, besides rheological activity, also in a whole range of application properties. Their manufacturing program includes the standard products Sillitin, Sillikolloid and puriss, the surface-treated Aktisil and the calcined products Silfit and Aktifit.

AKTIFIT AM is an activated SILFIT Z 91, produced by modifying the surface with amino functional silane. It is used as a functional filler either on its own or combined with extenders or matting agents. An optimum effect will be obtained in polar elastomers in combination with sulfur or sulfur donor, amine or bisphenolic crosslinking systems. This product can be used whenever high tensile strength and high modulus, combined with a very low tensile and compression set, are as important as excellent processing and extrusion properties. view less

AKTIFIT PF 115 is an activated SILFIT Z 91, produced by modifying the surface with a special amino functional silane. The by-products split off during the treatment reac-tion are largely removed during the production process which firmly at-taches the sil...view more
AKTIFIT PF 115 is an activated SILFIT Z 91, produced by modifying the surface with a special amino functional silane. The by-products split off during the treatment reac-tion are largely removed during the production process which firmly at-taches the silane to the filler sur-face. This helps minimize undesira-ble side effects, as they are poten-tially encountered with in situ mix-ing (direct addition of silane to the compound). view less

AKTIFIT Q is an activated SILFIT Z 91, produced by modifying the surface with a methacrylic silane. The by-products split off during the treatment reaction are largely removed during the production process which firmly attaches the silane to the filler surface.

GLOXIL iM16k MAM is a micro hollow glass sphere whose surface has been modified with a special methacrylic functional group. The process parameters are selected in such a way that, on one hand, anchoring to the surface takes place and, on the other hand, released by-products are removed as far as possible during production. Undesirable by-products, such as occur during in-situ mixing, are therefore practically completely prevented. view less

The process parameters are selected in such a way that, on the one hand, anchoring to the surface takes place and, on the other hand, released by-products are removed as far as possible during production. Undesirable byproducts, such as occur during in situ mixings (i.e. during the direct addition of the additives), are therefore practically completely prevented and the material improves its hydrophobic properties. view less
