| 摘要 |
The invention relates to carbon black with a CTAB surface area from 10 to 35 m2/g and a DBP absorption from 40 to 180 ml/100g, the .DELTA.D50 value being greater than 340 nm. The carbon black is produced in a furnace-black reactor by a liquid carbon-black raw material and gaseous carbon-black raw material being injected in the constriction. The carbon blacks can be used in rubber mixtures, particularly in extrusion profiles.
