  • Carbon black and rubber composition containing same
    Patent number: 6228928
    Abstract: New carbon blacks that when incorporated into rubber compositions impart increased abrasion resistance and lower hysteresis. Also disclosed are rubber composition incorporating the novel carbon blacks, which have nitrogen surface area of at least 100, a CDBP of at least 105, a tint of 90-140 and a delta D50/Dmode ratio of 0.6-0.76.

  • Carbon blacks
    Patent number: 6156837
    Abstract: A process for producing carbon blacks comprised of mixing an oxidant, primary fuel, and carbon black feedstock to form carbon black particles and aggregates, passing the mixture through a reactor, cooling, separating, and recovering the carbon black product. The improvement comprises the addition of a secondary oxidant-containing stream to the reactor such that the secondary oxidant stream does not interfere with the formation of the carbon black particles and aggregates in the reactor. Also disclosed are new carbon black products defined by the following parameters:35 mg/g.ltoreq.I.sub.2 No..ltoreq.65 mg/g30 m.sup.2 g.ltoreq.CTAB.ltoreq.55 m.sup.2 g1.12 mg/m.sup.2 .ltoreq.I.sub.2 No./CTAB ratioTint.ltoreq.65%75 cc/100 g.ltoreq.CDBP.ltoreq.95 cc/100 gAlso disclosed are rubber and/or plastic compositions containing the new carbon blacks.

  • Low rolling resistance/high treadwear resistance carbon blacks
    Patent number: 5232974
    Abstract: Carbon blacks having a having a CTAB of 95-120 m.sup.2 /g, a CDBP of 106-120 cc/100 g, a Tint/CTAB ratio of 0.90-1.10, a Skewness D.sub.c of 1.30-1.80 and a Skewness P.sub.s of 1.00-1.50. Also disclosed are rubber compounds containing the carbon blacks which exhibit increased abrasion resistance, lower heat build-up and reduced rolling resistance.
