Title
(EN) Elastomeric compositions having improved appearance
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/100 g, 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.
