Silicone for the EMI and RFI Shielding Industry
Silicone materials for the EMI and RFI shielding industry are engineered for sealing and shielding applications requiring environmental resistance, electrical conductivity options, broad temperature stability, and long-term reliability in electronic systems. Silicone elastomers are widely used in conductive gaskets, EMI shielding gaskets, environmental seals, connector seals, custom molded rubber parts, and enclosure sealing systems designed to reduce electromagnetic interference and radio frequency interference. These materials are commonly specified in aerospace electronics, military systems, telecommunications equipment, medical devices, industrial electronics, and outdoor electronic enclosures.
