5750-S series - Electrically conductive rubber sheets

Electrically conductive rubber in general is known for its excellent weather, oxidation, and ozone resistance. In EMI shielding, this rubber in particular is used 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. 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 (Part number 5760) or Graphite conductive rubber (Part number 5755) from a costs point of view, while military and aerospace applications often call for Silver copper silicone conductive rubber (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, moulded parts, die-cut, strips, o-rings, etc.

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

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

How does the conductive filler material in the rubber compare to costs and performance?

Part number Conductive filler Cost Conductivity Typical shielding effectiveness*
5750 Silver plated aluminum $$$ Extremely conductive 120 dB
5760 Ni-graphite $$ Super conductive 100 dB
5755 Graphite $ Very conductive 70 dB

* More information about shielding performance can be found under "technical properties" (a few paragraphs up)
