Carbon Graphite Production Materials

CARBON GRAPHITE

Carbon Graphite materials are a composite of different carbon materials and inorganic additives which have exemplary performance in demanding applications in either wet or dry applications because of their unique combination of characteristics.

ELECTROGRAPHITE

Electrographite materials have been processed to extremely high temperatures to transform carbon raw materials to graphite and dramatically increase Thermal Conductivity, Electrical Conductivity, Oxidation Resistance, and Chemical Resistance.

Learn More

RESIN-BONDED GRAPHITE

Resin-bonded Carbon Graphite materials consist primarily of resin with varying degrees of carbon graphite injections to provide for specialized properties. These materials do not go through the coking and impregnation process.

SILVER-IMPREGNATED

Carbon Graphite or Electrographite can be modified through Silver impregnation. Molten Silver is impregnated into these base materials to impart additional benefits to the materials making them ideal for certain end-use applications.

COPPER & METAL GRAPHITE

This family of metals combines the high Electrical Conductivity of copper with other metal and graphite raw materials to produce proprietary materials with unique performance characteristics particularly suited for dynamic electrical transmission applications.

ANTIMONY-IMPREGNATED

Impregnation with Antimony is uniquely efficient at reducing porosity in carbon graphite materials and reduction in Blister formation particularly in light hydrocarbon and hot oil applications. This is due in part to the low Surface Temperature of the molten metal.

BABBITT-IMPREGNATED

Impregnating carbon graphite materials with babbitt materials increases the melting range to 433o F (223o C) to 479o F (248o C) which significantly constrains its application temperature limits and allows products to function significantly above the process temperature.
