Superior Graphite’s ThermoPURE™ product line includes purified natural and synthetic graphite, as well as calcined petroleum coke. These materials are thermally modified using a patented continuous thermal purification process.

ThermoPURE™ products offer high purity and consistency resulting in “Superior” lubrication, thermal and electrical conductivity.

ThermoPURE™ Products

Characteristics	Appearance	Applications	SEM
Carbon (LOI): 99.7 - 99.9% Grain Size Distribution: Varies upon grade	This material has a silvery sheen after purification. It has excellent thermal and electrical properties, and enhanced lubrication properties as a result of the impurities such as quartz, and iron being removed during the high temperature processing.	Energy Materials, Friction Materials, Lubricant Additive, Polymer and Rubber Composites, Packings & Seals, Thread Compounds, Powdered Metallurgy, Insulation.

Carbon (LOI): 99.7 - 99.9% Grain Size Distribution: Varies upon grade	Purified Petroleum Coke is produced with Superior Graphite’s patented high temperature furnace technology. This continuous process purifies petroleum coke at temperatures in excess of 2760°C, resulting in the final product. Due to its extremely high purity, particle morphology, and graphitic crystalline structure, it is a unique type of carbon.
