5750 series - Electrically conductive rubber Electrically conductive rubber in general is known for its excellent weather, oxidation and ozone resistance, but EMI Shielding in particular is used as a medium to provide electrical conductivity across a gasket-flange interface. Electrically conductive rubber is a rubber filled with small conductive metall parts to make the rubber conductive. It can make an EMI-proof and a pressure watertight seal in narrow constructions. Electrically conductive rubbers are typically specified for EMI applications. Commercial EMI applications often call for Nickel-Graphite Conductive Rubber (Partnumber 5760) or Graphite Conductive Rubber (Partnumber 5755) due to cost, whereas military and aerospace applications often call for Silver Copper Silicone Conductive Rubber (Partnumber 5750) to meet Mil-G-83528C specifications. Military or aerospace may also use fluorosilicone versions for its fuel and chemical resistance. Electrically conductive rubber is also used for EMP protection and against static electricity. Also available in fluor silicone conductive rubber for resistance against (hydraulic) oil and fuels. The rubber can be filled with silver, nickel, silvered glass, silvered aluminum or graphite (only for ESD). Also for wave-guide applications. As it shields high frequencies, electrically conductiver rubber shows a shielding effect of 60 dB at 30MHz ~ 10GHz. Owing to its excellent conductivity, grounding and EMI shielding effect, it is well suited for military communication equipment. It can be manufactured in various shapes such as sheets, moulded parts, die-cut, strips, o-rings, etc.
