Hoffmann Mineral

Visit Company Website
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.

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. veja menos
Struktosil 45 AM Hoffmann Mineral Struktosil 45 AM is a modified fine talc grade for use in elastomers and coatings. It improves in particular the barrier effect.

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. veja menos
