Functional Fillers for Elastomers, TPE, Thermoplastics, Molded Parts and Films
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.
