The following guide formulations show examples of the use of Neuburg Siliceous Earth in elastomer. Compounding ingredients, their concentrations and the overall results have, however, not been optimized for production purposes. Different or additional raw materials may be required for manufacturing suitable finished articles. In many cases, substituting Aktisil for Sillitin will lead to improved results. The guide formulations are based on European formulations with raw materials commonly used in Europe. For further information on these products, the raw material supplier should be contacted directly.
