Abstract
Non-ASTM low hysteresis carbon blacks chemically treated, and surface coated with a compound comprising at least one amine group and at least one thiol group, and/or di- and/or polysulfidic linkage. When compared with a standard ASTM grade compound, the disclosed surface modified low hysteresis carbon black compound shows improved rolling resistance, wet traction, and DIN abrasion, comparable to silica compounds.
