Natural rubber/silica technology can reduce the rolling resistance of truck tires

- Apr 30, 2019-

Evonik Industries A.G., a Hanover, Germany, maker of rubber reinforcement materials, has developed a silicon/silane technology for natural rubber compounds that it claims will help reduce rolling resistance in medium truck and bus tires.

Evonik claims that tests have shown that its silica/silane technology can save up to 8 percent on fuel and reduce braking distance compared to traditional carbon-enhanced natural rubber compounds, thereby improving driving safety on wet or snow-covered roads.

When used with synthetic rubber, the effect of silica on rolling resistance of passenger car tires has been well documented, Evonik noted.The company claims its Ultrasil 91000 gr precipitated silica reinforced filler is "particularly suitable" for use in truck and bus tires.

"As a result, silicon/silane technology, especially for high consumption of green tire, buses and trucks made an important contribution to climate protection," Evonik silicon rubber technical services department director Jens Kiesewetter said, "and, in the European Union is expected to reach a agreement on carbon emissions targets recent cases, silicon/silane technology made an important contribution to climate protection."The trucks are running out of oxygen."

Ultrasil 9100 gr is relatively easy to be incorporated and dispersed in natural rubber compounds despite its high specific surface area, Evonik points out.The resulting compounds provide better wear resistance, resulting in better mileage performance.

This is particularly important, etron says, because the coverage of long distance truck/bus tires and the infrastructure changes they have encountered place an especially heavy load on these tires.Evonik said the silicon-reinforced compounds could also improve driving safety by reducing braking distance, even on wet roads.

"Feedback from the market tells us that demand for green tires is still very high due to their advantages," said Bernhard Sch_fer, director of rubber and silicon materials.

"Their use in buses and trucks, particularly in buses and trucks, is still quite new and has attracted a lot of interest."

In addition, Evonik noted that a plant in adapazari, Turkey, is expanding its tire silica production capacity "entirely on track," including increasing Ultrasil 9100 gr precipitated silica packing and Ultrasil 5000 gr production capacity to optimize wet and winter performance of tires.

The expansion is in response to "the growing demand for innovative silicon" and primarily serves customers in southeast Europe and the Middle East.The project, which aims to increase capacity by 40,000 metric tons per year, is expected to be completed by the end of 2019.As a big supplier of rubber chemicals in North America market, Shenyang Sunnyjoint Chemicals Co., Ltd. will keep an eye on the market undulate fluctuate.
