120 years of Neuburg Siliceous Earth – how do you explain such an unprecedented success story?
The history of using silica goes back much further than 120 years. The ancient Romans already used it because of its refractory properties. Modern times associate the history of siliceous earth above all with the colour ultramarine blue, which was first produced in the 19th century using siliceous earth or kaolin. It was not until 1903, when interest in Neuburg Siliceous Earth as an ingredient in metal polishes increased, that my great-grandfather Franz Hoffmann started to extract, process, and sell this special raw material. The fact that this success story continues to this day is due, above all, to its versatility. As early as the 1920s, my grandfather and his brother became the second generation to enter the rubber industry. And Neuburg Siliceous Earth still continues to prove its strengths in a range of modern elastomers, for example, rubber profiles and seals.
