Last week, Sid Richardson Carbon & Energy Co. announced the introduction of a new modified carbon black called ES200 that that imparts lower hysteresis in rubber compounds without adversely affecting other properties such as treadwear. Lowering hysteresis is key to improving the rolling resistance of tires, thus improving fuel economy. Sid Richardson calls this new class of filler “Energy Saver Blacks” (patent and trademark pending).
According to the company, other advantages of ES200 include its compatibility with various rubber formulations (including natural rubber), higher rebound, especially at elevated temperatures, increased modulus, improved angle abrasion, and the further potential to improve properties through compounding.
