The conductive silicone gasket is made of metal powder and silicon. It has excellent EMI shielding effectiveness and environmental sealing and a long lifetime. The conductive fillers are nickel graphite,  silver glass, silver aluminum, silver copper. In addition to managing EMI emissions and susceptibility, conductive gaskets are used for environmental sealing. With proper compression, these gaskets can seal out the rain (NEMA 3), withstand pressure washing (IP65, IP66, NEMA 4X), and prohibit water ingress during submersion (IP67, NEMA 6).
