Carbon filled conductive rubber sheet

The rubber is made conductive by incorporating small conductive carbon particles throughout the material. It can provide an EMI-proof and watertight seal in narrow constructions.

5755-S Electrically conductive carbon filled rubbers are typically used for ESD and EMI shielding applications.

Due to its quite excellent conductivity, grounding, and EMI shielding effect, it is well suited for ESD application in electronics equipment. The rubber can be manufactured in various shapes such as sheets, molded parts, die-cut, strips, o-rings, etc.

Electrically conductive rubbers are typically used for EMI applications. But they are also useful for EMP protection, wave-guide applications and against static electricity.
Commercial EMI applications often choose Graphite conductive rubber (Part number 5755). 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.

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?
