5750-P series - Electrically conductive rubber profiles

Electrically conductive rubber profiles in general are 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 in these profiles is made conductive by means of small conductive metal particles, distributed throughout the rubber. It can provide an EMI-proof and a pressure watertight seal in narrow constructions.

Electrically conductive rubbers are typically used for EMI applications. Also used 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 call for Nickel-Graphite Conductive Rubber (Partnumber 5760) or Graphite Conductive Rubber (Partnumber 5755) due to costs, whereas military and aerospace applications often call for Silver Aluminium Silicone Conductive Rubber (Partnumber 5750) to meet Mil-G-83528C specifications. In military or aerospace, fluorosilicone versions may also be used for its chemical and fuel resistance.

As the material shields high frequencies, electrically conductiver 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 communication 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 pick 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 is the conductive filler material in the rubber connected to costs and performance?
