Abstract: Carbon blacks such as reinforcing-grade carbon blacks with high structure are described. The carbon black can have the following properties: a statistical thickness surface area (STSA) ranging from 80 m 2 /g to 150 m 2 /g, an oil absorption number (OAN) of at least 180 mL/100 g, and a crushed oil absorption number (COAN) of at least 110 mL/100 g. Rubber compounds which incorporate the carbon black also are described.

Abstract: Disclosed herein are elastomer compounds comprising: at least one elastomer that is resistant to heat for 70 h at 100°C such that the at least one elastomer exhibits at least one of the following properties selected from: (a) a change in durometer hardness of no more than 15 points, (b) a change in tensile strength of no more than 40%, and (c) a change in ultimate elongation of no more than 40% The elastomer compound further comprises at least one graphene-based material present in an amount ranging from 0.01 phr to 30 phr relative to the at least one elastomer and at least one carbon black present in an amount ranging from 15 phr to 150 phr relative to the at least one elastomer. Also disclosed are methods of making such compounds, and articles comprising elastomer compounds.
