Product category: Siliceous earth

Neuburg Siliceous Earth

Classic Neuburg Siliceous Earth is a natural combination of corpuscular Neuburg silica and lamellar kaolinite: a loose mixture impossible to separate by physical methods. 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.

Besides the standard products Sillitin and Sillikolloid, there are calcined variations, named Silfit and the activated, surface treated products, Aktisil and Aktifit.

Product category: Aktisil

Activated products for high performances

These special fillers are based on Neuburg Siliceous Earth, the surface of which is treated with chemical agents, mostly silanes. The AKTISIL and AKTIFIT products have largely functional groups that enable covalent bonds or intensive interaction with the polymer matrix and produce special effect. The following properties can be significantly improved: tensile strength, tensile modulus, tension and compression set, abrasion resistance, resistance to fuids, electrical resisitivity and dielectric loss after exposure to water.
