Nano-structure blacks - A new carbon black family designed to meet truck tire performance demands

Nano-structure blacks are a new carbon black family produced by physical su rface modification in a furnace reactor. Various grades with altered specif ic surface areas and structure levels are now available. The main character istics of these novel blacks is a unusually rough surface which leads to en hanced interaction forces with rubbers. Due to a narrow aggregate size dist ribution with limited amounts of large aggregates not only hysteresis but a lso treadwear is improved compared to conventional blacks. This makes nano- structure blacks particularly suitable for usage in truck tire applications .
