Abstract
Un boitier pour matériel électrique ou électronique est obtenu par moulage à chaud d'une composition comprenant une résine organique thermodurcissable qui contient du graphite expansé en quantité suffisante pour conférer au produit moulé une résistivité électrique n'excédant pas 10 ohms-cm. Ce boitier a une excellente aptitude à atténuer le rayonnement électromagnétique émis par le matériel qu'il abrite et à protéger celui-ci contre le rayonnement électromagnétique d'origine extérieure.
