Disclosed herein are elastomer compounds comprising: at least one elastomer that is resistant to heat for 70 h at 100&#xb0; 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.

Elastomer compounds

A compounded elastomer comprising an elastomeric resin, a first carbon black, and a second carbon black different from the first carbon black. The second carbon black is a partially crystallized carbon black having an OAN structure of greater than 120 cm/100 g and less than 200 cm/100 g, a surface energy of less than 10 mJ/mand a Raman microcrystalline planar size (L) of greater than or equal to 25 &#x212b; and less than or equal to 50 &#x212b;.
