Cabot Corporation announced the global launch of its new PROPEL® E8 engineered reinforcing carbon black designed to provide superior tread durability at low rolling resistance for high-performance tire tread applications. This new product addresses the unique challenges posed by the heavier weight and higher torque of electric vehicles (EVs) compared to traditional internal combustion engine (ICE) vehicles. The PROPEL E8 grade complements Cabot?s existing solutions within the PROPEL E series, which are also suitable for use in high-performance tires.

The treads of EV tires require a performance balance difficult to meet with traditional, high surface area ASTM carbon blacks. The PROPEL E8 solution enables better rolling resistance when compared to ASTM N200 and N100 carbon black grades. It also provides high stiffness and modulus with abrasion resistance equal to ASTM N100 series carbon black.

The PROPEL E8 grade complements the other solutions in its PROPEL E portfolio including grades PROPEL E3, PROPEL E6 and PROPEL E7, which can also deliver performance and sustainability benefits for various high-performance tire formulations. Cabot?s PROPEL E series is comprised of high surface area, medium structure reinforcing carbon blacks specifically engineered to increase the overall sustainability of the tire value chain, enabling tread formulators to deliver tires with low rolling resistance for maximum range while enhancing tread durability to extend tire life span, resulting in fewer EOLTs. In addition, PROPEL E3 carbon black considerably reduces hysteresis enabling low rolling resistance, which is a critical design consideration for EV tires to maximize range.
