    Abstract: Graphene is an allotrope or one of the several physical forms of carbon, other examples being graphite, fullerenes, and diamond. At the atomic level, it is in the form a sheet with a thickness nominally under 1.0 nanometer and up to 1 micron in diameter. Sheets of such dimensions when added to other composites facilitate increases in thermal and electrical conductivity and in the case of elastomer nanocomposites, improvements in hysteresis, compounding ingredient dispersion, aging resistance, and reductions in permeability. In the case of conveyor belt cover compounds, natural rubber based formulations are preferred due to high tensile strength, tear strength and damage resistance, and high resistance to abrasion. Graphene as a performance additive enables further improvement in these critical properties.
