ULTRASIL® 7800 GR is a custom-tailored silica made by Evonik for use in particularly large SUV tires as well as high-mileage all-season tires. By developing ULTRASIL® 7800 GR, a silica with a customized surface area that meets the extreme demands of SUV and all-season tires, Evonik has now taken the next step in innovation.
“The challenge for SUV tires is to give the tires sufficient stiffness in spite of their size,” explains Dr. Hark-Oluf Asbahr, Marketing of Rubber Silica. “With ULTRASIL® 7800 GR, we managed to find the right mix to combine joy of driving, road safety, and resource efficiency in a single product.”
Since the United States is the largest sales market for SUVs, ULTRASIL® 7800 GR will be produced there for now. Evonik has responded to the rising demand for silica by building a new production facility in Charleston, South Carolina. The new silica plant is expected to become operational in mid-2018.
More information about the Silica/Silane technology of Evonik will be available at the stand of Evonik Resource Efficiency GmbH (Stand C 240) at the Tire Technology Expo in Hanover from February 20-22, 2018.
