emi gasket sheet is made conductive by incorporating small conductive metal particles throughout the material.
It can provide an EMI-proof and watertight seal in narrow constructions.
Electrically conductive rubbers are typically used for EMI applications. But they are also useful for EMP protection, wave-guide applications and against static electricity. The rubber can be filled with silver, nickel, silvered glass,
silvered aluminium, or graphite (only for ESD) Commercial EMI applications often choose Nickel-graphite conductive rubber . or Graphite conductive rubber from a costs point of view,
while aerospace applications often call for Silver copper silicone conductive rubber to
meet
Mil-G-83528C specifications. In aerospace, fluorosilicone versions may also be used due to their chemical and
fuel resistance.
As the material shields high frequencies, electrically conductive rubber shows a shielding effect of 60 dB at 30MHz ~ 10GHz. Due to its excellent conductivity, grounding, and EMI shielding effect, it is well suited for communications equipment. The rubber can be manufactured in various shapes such as sheets, moulded parts, die-cut, strips, o-rings, etc.
