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.

Carbon black, method for the production thereof, and use thereof

A carbon black having an average particle diameter of 13 nm or shorter, Dmod of 80 nm or shorter, D1/2/Dmod of 0.6 or below, and a pH of 5 or higher.

Carbon black and process for producing the same

Novel carbon blacks are described wherein the carbon blacks have a nitrogen surface area of from about 65 to about 95 m2/g; an Iodine number without additive of from about 64 to about 120 mg/g; a tinting strength of about 90 % or less; and a particle size of from about 22 nm to about 39 nm. Polymeric compositions containing at least one polymer and the carbon blacks of the present invention are further described as well as preferred polymeric compositions, such as wire and cable compounds containing the carbon blacks of the present invention in such uses as shielding compositions. Electrical conductors containing one or more layers which contain the carbon blacks of the present invention are further described as well as improved properties using the carbon blacks of the present invention.

Carbon blacks useful in wire and cable compounds

The invention relates to a rubber composition for a tire tread simultaneously establishing a high wear resistance and a low heat buildup, and more particularly to a rubber composition for a tire tread comprising 10-250 parts by weight of a carbon black per 100 parts by weight of a rubber component, in which said carbon black is produced in a carbon black production step satisfying the following relational equations (1) and (2):
 
200≦α≦900  (1)
 
−25 x α+850≦β≦900  (2)
 
when a residence time from the introduction of the starting hydrocarbon into the high-temperature combustion gas flow to the introduction of the quenching medium is t1 (sec), an average reaction temperature for such a time is T1 (° C), a residence time from the introduction of the quenching medium to the enter of a reaction gas flow into the reaction stop zone is t2 (sec), an average reaction temperature for such a time is T2 (° C), α=t1×T1 and β=t2×T2

Rubber composition for tire tread and pneumatic tire using the same

Ink jet ink containing at least one pigment and at least one oxidized carbon black. The ink jet ink is prepared in a process wherein the pigment is dispersed in at least one solvent, followed by addition of the oxidized carbon black and renewed dispersing. The ink jet ink can be used for printing textiles, metal, foil, film, sheet, glass and paper.

Ink Jet ink

Carbon blacks having a CTAB of greater than 155 m2/g; an I?2?No. of greater than 180 mg/g; a N2SA of greater than 160 m?2?/g; a Tint value of greater than 145 %; a CDBP of 90-105 cc/100 g; a DBP of 115-140 cc/100 g; a ΔDBP (ΔDBP = DBP - CDBP) of 20-35 cc/100 g; a ΔD50 of less than 40 nm; a Dmode of 40-65 nm; ΔD50/Dmode ratio of 0.55-0.67; and an ASTM Aggregate Volume less than 137,000 (nm)3. Also disclosed are rubber compositions containing the carbon blacks which exhibit superior handling and cornering performance properties, increased abrasion resistance and improved traction.
