Why is Duocel® Reticulated Vitreous Carbon (RVC) foam so special?
The matrix of cells and ligaments is completely repeatable, regular, and uniform throughout the entirety of the material. Duocel® Reticulated Vitreous Carbon is a rigid, highly porous and permeable structure and has a controlled density of carbon per unit volume.

*these values were derived from small samples where edge effects influenced the results. Larger samples having a minimum of 10-15 bubble diameter produce more general test results which are in better compliance with the equations.
Duocel® Reticulated Vitreous Carbon (RVC) is not thermally conductive and can be used as an insulator. Duocel® RVC is able to withstand extreme temperatures in non-oxidizing atmospheres.
Please visit our thermal conductivity page in the technical data section for a more in depth explanation of how materials and properties effects the thermal conductivity of Duocel® foam.
The compression strength of Duocel® Reticulated Vitreous Carbon ( RVC) is dependent upon pore size. The smaller the pore size the stronger the foam. The compression strength ranges from 20 to 80 psi.

Duocel® Reticulated Vitreous Carbon ( RVC) is made in a 3% relative density (of it’s parent material), or it has 97% void volume. The resulting foam structure is extremely lightweight.
Duocel® Reticulated Vitreous Carbon ( RVC) is uniquely strong at elevated temperatures. It also has a high scratch resistance at 6-7 mohs.
Duocel® Reticulated Vitreous Carbon (RVC) is composed of one of the most chemically inert forms of Carbon. Duocel® RVC is highly resistant to intercalation by materials which disintegrate graphite.
Duocel® RVC is inert to a wide rage of very reactive acids, bases, and organic solvents. At high temperatures it will form carbides, but is inert to non-carbide forming metals
Duocel® RVC is manufactured at 3% relative density and is made in a billet size of 6” x 12” x 24”. ERG does have the capability to create larger billet sizes on a custom basis.
The cost for Duocel® RVC is about $1.50 per cubic inch. This is the cost before any fabrication or machining is done to the material.
ERG does not sell foam as a raw bulk material, only as finished end item components.
