发明名称 Rheology regulators such as ground natural calcium carbonates optionally treated with a fatty acid or salt and the use thereof
摘要 Described is a selection of an ultrafine natural calcium carbonate, optionally treated with one or several fatty acids or one or several salts or mixtures thereof, and its use as rheology regulator for polymer compositions. The B.E.T specific surface area according to ISO standard 4652 is 14 to 10 m2/g, and the oil absorption is higher than 16 measured according to the ISO 787-V standard (Rub- out method). The use of the ultrafine calcium carbonate enhances the conditions for mixing the constituents and manufacturing as well as the properties of the end product.
