Patent ID: 8034316

Claim:
A carbon black having a low PAH content, wherein the PAH content is determined based on a PAH22 content, said carbon black is a furnace carbon black and has a STSA, I 2 No/STSA ratio, and PAH content as follows: a) STSA: 110-250 m 2 /g I 2 No (mg/g)/STSA (m 2 /g): 1.20 to 0.70 PAH: 400 ppm or less; or b) STSA: 80-110 m 2 /g I 2 No (mg/g)/STSA (m 2 /g): 1.15 to 0.70 PAH: 30 ppm or less; or c) STSA: 65-75 m 2 /g I 2 No (mg/g)/STSA (m 2 /g): 1.10-0.88 PAH: 500 ppm or less DBP: 115-125 mL/100 g; or d) STSA: 65-80 m 2 /g I 2 No (mg/g)/STSA (m 2 /g): 0.70 to 0.88 PAH: 500 ppm or less; or e) STSA: 1 to 35 m 2 /g I 2 No (mg/g)/STSA (m 2 /g): 1.40 to 0.70 PAH: 50 ppm or less; or f) STSA: 70 to 90 m 2 /g I 2 No (mg/g)/STSA (m 2 /g): 1.00 to 1.20 PAH: 50 ppm or less DBP: 60-80 mL/100 g; or g) STSA: 87-95 m 2 /g I 2 No (mg/g)/STSA (m 2 /g): 0.91 to 1.08 PAH: 100 ppm or less DBP: 109-119 mL/100 g, wherein said carbon black has one or more of the following mechanical properties or rubber properties when included in a rubber formulation according to ASTM D 3191-02: abrasion resistance (21% slip) of from 80 to 170; elongation (%) of from 300 to 600; tensile strength (Mpa) of from 20 to 35; 100% modulus (Mpa) of from 2.4 to 4.5; 300% modulus (Mpa) of from 12 to 23; ratio of 300% modulus/100% modulus (M300%/M100%) of from 3.5 to 6; bound rubber (%) of from 15 to 30; and/or max tan delta @ 0° C. of from 0.25 to 0.4.
