| 20110244384 | CARBON BLACK GRANULATE, METHOD FOR PRODUCING CARBON BLACK GRANULATE, AND USE THEREOF - The invention relates to carbon black granulates having an APC value, measured at a conveying speed of 8 m/s and a solid load of 27 g/kg, less than or equal to 20 and a 25 [mu]m pressure filter value of less than 5 bar cm2/g. The carbon black granulate is produced by carbon black powder being pre-granulated in a first mixing granulator with addition of a granulation liquid with or without binders and being granulated to a finished state in a second mixing granulator without further addition of granulation liquid. The carbon black granulate can be used as a filler, reinforcing filler, UV stabilizer, conductive carbon black, pigment, or reducing agent. | 10-06-2011 |
| 20110236816 | CARBON BLACK, METHOD FOR THE PRODUCTION THEREOF, AND USE THEREOF - The invention relates to carbon black having a C-14 content greater than 0.05 Bq/g and a ratio ΔD50/Dmode of the aggregate size distribution of less than 0.7. The carbon black is produced by thermal oxidative pyrolysis or thermal cleavage of the carbon black raw material in that the carbon black raw material contains renewable carbon black raw materials and an oxygen deficiency is present in the pyrolysis/cleavage reaction. The carbon blacks can be used in rubber and rubber mixtures, plastic, printing inks, inks, inkjet inks, toners, lacquers, paints, paper, adhesives, batteries, pastes, bitumens, concrete, and other building materials and as reducing agents in metallurgy. | 09-29-2011 |
| 20110232531 | Pigment Granulate, Method for Producing the Same and Use Thereof - The invention relates to a pigment granulate which contains 40 to 65% by weight of pigment and at least 10% by weight of a compound of general formula (I) CH | 09-29-2011 |
| 20110207872 | Carbon Black, Method for the Production Thereof, and Use Thereof - The invention relates to a carbon black with a CTAB surface area of from 20 to 49 m | 08-25-2011 |
