DESCRIPTION: PORCUPINE METALASTIC is available in two forms: EMI shielding with pressure seal and EMI shielding only. Shielding is provided by severely expanded monel foil. For composite shielding and pressure sealing, the expanded monel is filled with a silicone elastomer. The material gains its excellent compressibility from very uniform thickness. The expanded monel provides dozens of contact points per square inch of surface area, assuring moderate shielding effectiveness.
