Message: | EMI / RFI gasket materials are used to attenuate electronic emissions from electronics and electro-mechanical devices. Electrically conductive gaskets/EMI shielding gaskets are most commonly applied to enclosure covers, doors and penetrations to prevent or restrict electromagnetic emission that can interfere with other electronic components. Critical devices are also tested for EMI susceptibility, ensuring external EMI and RFI emissions do not interfere with the function of the device.
In addition to managing EMI emissions and susceptibility, the conductive gaskets are used for environmental sealing. With proper compression, these gaskets can seal out rain (NEMA 3), withstand pressure washing (IP65, IP66, NEMA 4X) and prohibit water ingress during submersion (IP67, NEMA 6).
EMI shielding materials are an extension of silicone rubber capabilities – EMI gaskets can be die cut, water jet cut or compression molded from electrically conductive silicone rubber compounds with age and weather resistance or conductive fluorosilicone rubber for additional chemical resistance. url:http://www.rubberplasticparts.com |
