Rhodia says silica grades boost tires' energy efficiency
HILTON HEAD ISLAND, S.C. (April 23, 2012)—Rhodia Inc. has introduced Highly Dispersible Silica grades that it claims will improve tires' rolling resistance up to 25 percent and vehicle gas mileage by up to 7 percent.
The new silicas will also measurably lower vehicle emissions through improved tire performance without sacrificing tire wear, traction or grip on wet surfaces, said Soline de Cayeux, Rhodia silica business development manager, in a technical presentation at the 28th annual Clemson University Tire Industry Conference held April 18-20 at Hilton Head.
“Silica is already a well-established ingredient for improving tire performance,” De Cayeux said. “Rhodia's new HDS takes tire performance to a new level.”
De Cayeux presented test data demonstrating the superior performance of HDS in reducing tire rolling resistance while maintaining product quality.
Until recently, Rhodia HDS—available in the ZS and ZS Premium ranges of products—have been used primarily in passenger tire vehicle treads, according to De Cayeux.
“Now we see increasing customer interest in the use of certain HDS for non-tread applications, like sidewalls, to further increase fuel efficiency,” she said. The ZS range of HDS is also finding increasing acceptance in heavy duty, off-the-road and long haul tires, she said.
