Abstract
(EN)
Compositions comprising an elastomer and a carbon black are disclosed, which may be used to form articles having higher gloss and/or jetness than articles formed using an industry standard carbon black such as N650. The carbon blacks may be characterized by an I2No. of from about 80 to about 400 mg/g, a DBP value of from about 50 to about 175 cc/100g, a tint value of from about 100 to about 175 %ITRB, a N2SA value of from about 80 to about 450 m2/g, and/or a CTAB value of from about 80 to about 300 m2/g. Also described are articles made from the composition, and processes for making the article.
(FR)
L'invention concerne des compositions renfermant un élastomère et du noir de carbone, ces compositions pouvant être utilisées pour fabriquer des articles présentant un brillant et/ou une aptitude à former un jet améliorés par rapport aux articles préparés à l'aide d'un noir de carbone industriel standard, par exemple N650. Les noirs de carbone de cette invention se caractérisent par leur aire I2No. qui varie environ entre 80 et 400 mg/g, leur valeur DBP qui se situe approximativement entre 50 et 175 cc/100g, leur indice de coloration situé entre 100 et 175 % ITRB environ, leur valeur N2SA oscillant entre 80 et 450 m2/g, et/ou leur valeur CTAB allant de 80 à 300 m2/g. Cette invention concerne également des articles fabriqués à l'aide de cette composition, ainsi que des procédés de fabrication de ces articles.
