An unrefined surface modified low hysteresis carbon black (SMLHCB) product is described herein. The unrefined surface modified low hysteresis carbon black product contains a low hysteresis carbon black having a surface that has been modified with from about 0.1 to about 50 wt % of a surface modifier attached thereto, wherein the surface modifier comprises an amino acid and at least one amine group.

Surface modified carbon black to simultaneously improve rolling resistance, wet traction, and wear resistance

A non-ASTM low hysteresis carbon black 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 is herein disclosed. The surface modified low hysteresis carbon blacks are post treated to remove excess surface modified compound to form refined surface modified low hysteresis carbon blacks.

Refined surface modified carbon black and methods of making same

A method of producing a surface modified low hysteresis carbon black (SMLHCB). The method includes treating a surface of a low hysteresis carbon black with from about 0.1 to about 50 wt % of a surface modifier to form the SMLHCB. The surface modifier includes an amino acid and at least one amine group.

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.
