CHESTER, Pa.—Evonik Industries plans to hike production capacity for precipitated silica by 22,000 metric tons by 2014 at its Chester facility to meet demand from tire manufacturers.
The project follows expansion increases in Europe and Asia by Evonik, which said it intends to boost its silica production by 30 percent from 2010 to 2014.
Precipitated silica is used to reduce rolling resistance in tires.
"Evonik's silica system substantially reduces consumption, achieving about 8 percent higher fuel savings compared to conventional car tires," said Burkhard Zoller, senior vice president of inorganic materials in North America for Evonik.
Silica, besides being used in tire tread, also is an ingredient in the food and animal feed industries and paints and coatings.
