Conductive Rubber Sheets

Conductive Rubber Sheets

Conductive Rubber Sheets 5750-S

This rubber is particularly used in EMI shielding as a medium to provide electrical conductivity across a gasket-flange interface

The rubber 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. 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 aluminum, or graphite (only for ESD). Commercial EMI applications often choose Nickel-graphite conductive rubber (Part number 5760) or Graphite conductive rubber (Part number 5755) from a costs point of view while military and aerospace applications often use silver plated aluminum (Part number 5750) to meet Mil-G-83528C specifications. In military or 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 military communications equipment. The rubber can be manufactured in various shapes such as sheets, molded parts, die-cut, strips, o-rings, etc.


  • Excellent conductivity on the entire surface
  • Excellent electromagnetic shielding effect
  • Easy die-cutting, kiss-cutting and slitting
  • Temperature ranges of -60 to +185°C
    (under certain circumstances, tolerance can be up to 220°C

What questions need to be answered to select the right material?

  • What approximate shielding effectiveness do you need to achieve for your application?
  • What environment will this material be exposed to? Does the rubber need to be solvent or fuel resistant (fluorosilicone)?
  • Are you looking for a semi-conductive/static dissipating material or is this a true EMI/RFI shielding application?
