HOFFMANN MINERAL is a German manufacturer of a natural mineral filler, named Neuburg Siliceous Earth, which is a 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. The unique structure leads to good application properties. This functional filler is sold worldwide under its trade name SILLITIN and SILLIKOLLOID and surface treated AKTISIL. Our calcined products SILFIT and AKTIFIT are based on the standard product SILLITIN Z 86. A thermal process is used to expel the crystalline water in the kaolinite portion and new mineral phases are formed practically amorphous. The silica portion remains inert at the temperature used. The resulting products have an outstandingly high degree of white and color neutrality. The Tailored Filler Solutions product GLOXIL is now expanding this portfolio in order to give customers the opportunity to differentiate themselves from the competition with tailored products in existing applications. HOFFMANN MINERAL has been working in cooperation with 3M for years to develop products based on hollow glass microspheres. The product is based on the iM16k, modified with a special functional group.
