KINGWOOD, Texas (June 22, 2016) — Orion Engineered Carbons L.L.C. recently introduced three rubber carbon black products for more fuel-efficient tires.
The new grades, Orion said, are in response to consumer demand and federal standards for vehicle fuel economy. The grades, with narrow aggregate size distribution (ASD), can help reduce rolling resistance via narrow particle size distributions and lower sidewall hysteresis, Orion said.
They also are claimed to lower air permeation “through the inner liner for better tire inflation consistency.”
“Compared to standard ASTM grades, a carbon black with narrow ASD features better in-rubber properties,” said Jose Briones, Orion's marketing manager, rubber, for North America.
In a presentation at the Carbon Black World in Fort Worth, Texas, on May 25, Mr. Briones said treadwear could be improved by up to 13 percent with narrow ASD carbon black technology.
Looking ahead, he urged the industry to develop partnerships to incorporate narrow ASD carbon blacks in the latest tire design concepts, including reduced tread depths and multi-layer tread designs.
Mr. Briones also called for studies to determine the benefit of narrow ASD carbon blacks in treads containing silica to further reduce rolling resistance.
