In the past decades, the rapidly expanding automobile industry has required in­creasing numbers of tires, black pigmented plastics and black paints with various characteristics. This has led not only to the development of new rubber grades, but also to the development of new carbon blacks required by refined application processes and to the development of a new and better manufacturing process, the furnace-black-process. This process allows the production of nearly all types of car-

bon black required from the industries using rubber, plastics, paints and inks. It also meets the high economic and ecological requirements of the present times.
