Abstract

The invention relates to black having a CTAB surface area of 100 to 160 m?/g, a quartile ratio of more than 1.60, and an FP index of >0. Said black is produced in a furnace reactor. Sixty to 90 percent by weight of the raw black material are injected into the reactor in the first third of the reaction zone, while the remaining amount of the raw black material is injected into the reactor upstream at least in one other point. In addition, the combustible is conducted such that 90 to 100 percent by weight of the combustible are evaporated when first hitting the raw black material and 80 to 99 percent by weight of the combustible are evaporated 5 ms before hitting the raw black material. Said blacks can be used in rubber mixtures.
