Evonik develops silica technology that could lower truck rolling resistance

Filed under: Silica, Tires — Notch @ 11:44 am

Evonik Industries A.G. announced that it has developed a silica/silane technology that can be used in natural rubber compounds to reduce the rolling resistance in medium truck and bus tires.

Evonik said that it conducted tests which proved that the use of its proprietary silica/silane technology could help improve fuel economy by as much as 8 percent when compared to traditional carbon-black reinforced NR compounds. Its use also helped reduce braking distances, thus making it safer to drive on on wet or snow-covered roads.

Jens Kiesewetter, Evonik’s head of technical service for rubber silica, said that when silica/silane technology is used in green tires for buses and trucks with high fuel consumption levels, it can make a significant contribution to climate protection, especially in light of the recent EU agreement on targets for CO2 reduction for trucks.

Evonik also announced that it is well on track to expand tire silica capacity at a plant in Adapazari, Turkey, including adding capacity for the Ultrasil 9100 GR precipitated silica reinforcing filler and Ultrasil 5000 GR, for optimizing wet and winter properties of tires.
