Title (EN) IMPROVED PERFORMANCE CARBON BLACKS
(FR) NOIRS DE CARBONE A PERFORMANCES AMELIOREES
Abstract: front page image
(EN)Carbon blacks having a CTAB of greater than 155 m?2¿/g; an I¿2?No. of greater than 180 mg/g; a N¿2?SA 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 $g(D)DBP ($g(D)DBP = DBP - CDBP) of 20-35 cc/100 g; a $g(D)D50 of less than 40 nm; a Dmode of 40-65 nm; $g(D)D50/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.
(FR)Noirs de carbone ayant un indice d'absorption du bromure d'ammonium de cétyle-triméthyle (CTAB) supérieur à 155 m?2¿/g; un indice I?2¿/g supérieur à 180 mg/g; une surface N¿2? supérieure à 160 m?2¿/g; un pouvoir colorant supérieur à 145 %; un indice de dibutylphtalate broyé (CDBP) de 90-105 cc/100 g; un indice de dibutylphtalate (DBP) de 115-140 cc/100 g; un $g(D)DBP($g(D) DBP=DBP-CDBP) de 20-35cc/100 g; un $g(D)D50 inférieur à 40 nm; un Dmode de 40-65 nm; un rapport $g(D)D50/Dmode de 0,55-0,67; un volume d'agrégats ASTM inférieur à 137'000 (nm)?3¿. On décrit aussi des compositions de caoutchouc contenant des noirs de carbone présentant de meilleures performances de maniabilité et de tenue de route en virage, une résistance à l'abrasion accrue et une traction améliorée.
