Patent ID: 8895142

Claim:
A carbon black having: a) a nitrogen BET surface area (BET) of 650 m 2 /g to 2,050 m 2 /g; b) a dibutyl phthalate adsorption value for the carbon black determined after controlled compression (CDBP value) in mL/100 g of from (−2.8+(b*BET)) to (108+(b*BET)), where b is 0.087 and BET is expressed in m 2 /g; and c) an apparent density (ρ, g/cm 3 ) of at least 0.820+q*BET, where q=−2.5×10 −4 , as determined at a compressive force (P) of 200 kgf/cm 2 on dry carbon black powder.
