  • Surface modified carbon black to simultaneously improve rolling resistance, wet traction, and wear resistance
    Patent number: 11945956
    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.
    Type: Grant
    Filed: May 16, 2023
    Date of Patent: April 2, 2024
    Assignee: Continental Carbon Co.
    Inventors: Raymond Soufiani, Eduardo Vega, Jr., Lashan Madusha Hendavitharanage De Silva, Frank E. Welsh, Luis P. Chibante
