Electromagnetic shielding

Along with natural electromagnetic fields such as sunlight, there are also those emitted by technical devices and facilities. Wherever there is wireless communication, there are high-frequency fields from cell-phone networks, television, and WLAN. Insulating graphite building materials can almost fully prevent excessively high loads from electromagnetic fields on the inside of buildings. These materials consist of plaster or clay and ECOPHIT®, a granulate or powder consisting of expanded graphite. The panels and plastering benefit from the extraordinary conductivity of natural graphite, which absorbs the electromagnetic radiation. This positive effect is already noticeable at low material strengths. A 10-millimeter thick graphite-modified plasterboard, can reduce radiation by up to 99.99 percent.
