Carbon foam for electromagnetic shielding and absorption for reasons that are both mechanical and electrical in nature. Electromagnetic shields are typically made from conductive metals, which are heavy and corrode in salt water. Carbon foam shield must be thicker than a conventional copper shield, but its lower areal density will make the weight of both shields nearly equal.

Carbon foam made from less expensive precursor materials such as coal are currently being made on a larger scale, and are now competitively priced in such applications as composite cores, fire and thermal protection, composite tooling, electromagnetic shielding, and radar absorption. These applications depend on one or more critical characteristics such as weight, mechanical properties, fire resistance, low smoke toxicity, or coefficient of thermal expansion.

Carbon foam shielding applications used wide range of conductivity means that carbon foam can be made conductive enough to make an effective shield. EMI shield testing has recently been conducted for Carbon Foam, and standard shielding parameters for certification were run from 100 MHz thru 18 GHz. The military with a lighter, more corrosion-resistant material than is currently.

Carbon Foam potential applications Low-cost carbon foams have also been identified as possible candidates in applications such as space borne mirror substrates and thermal protection; fuel cell anode/cathode gas diffusion layers and catalyst support; and lithium-ion batteries.

We used carbon foam for electromagnetic shielding application to enhance the mechanical and thermal strength. Fortunately, we found very excellent desired results.
This material ships as dry granules or powder. Each grade contains particles with an average thickness and surface area. All dimensions represent median sizes and there is a distribution around the mean. Carbon Foam by Nanoshel.
