Conductive foam is similar to standard packaging foams but with one crucial difference – the addition of carbon to the polymer mix during the manufacturing process to provide a high level of conductivity. This allows any electric current to pass through the cell structure of the foam and away from the component. Generally, the foam will have permanent conductive performance, meaning it is ideal for multi-trip packaging and in-plant handling applications. Its performance isn’t affected by atmospheric conditions. http://www.foam-metal.net/conductive-foam/
