DUSSELDORF, Germany (Jan. 2)—Degussa A.G. has acquired a 25-percent share of Turkish precipitated silica maker Egesil A.S. and plans eventually to take a majority stake in the firm. Egesil, based in Adapazari, near Izmit, has an annual production capacity of about 8,000 tons of silica, mainly for tire, technical rubber goods and emulsion paint applications. Degussa said this capacity level will increase to around 15,000 tons, backed by the introduction of new manufacturing technologies for high-performance tire silicas. "In keeping with our global activities, this step strengthens our market position for precipitated silicas and silicates in southeast Europe and in the Middle East," said Carl Voigt, executive vice president of Degussa's Coatings & Advanced Fillers Division. Degussa claims to be world's biggest supplier of precipitated silicas and silanes for the rubber industry and the second largest manufacturer of rubber and pigment carbon blacks. Its advanced fillers and pigments business reported sales of $1.1 billion in 2000, about 7 percent of overall group sales.
