Conductive Rubber and EMI

Conductive rubber is a standardized term that refers to any type of rubberized material that is capable of conducting electricity and eliminating electromagnetic radiation. There are three types of conductive rubbers that are used to mitigate electromagnetic interference: Multicon rubber, conductive elastomer, and rad thin. Each material is unique in its composition and its performance.

Multicon materials are the most predominantly used form of conductive rubber to date.  This material is offered either in a solid or sponge silicon form and uses Monel or aluminum wires to increase conductivity.

Conductive Elastomers is primarily formed into a flat shielding gasket and is only provided in a variety of different extruded profiles. The most common shielding gasket configuration is extruded as a solid cross section.

Rad thin is not as popular as the aforementioned multicon or conductive elastomer materials, but is a valuable shielding gasket that has the capacity to withstand a large variety of temperatures. This type of conductive rubber is commonly used as a shielding gasket for connecters.

EMI Gasket

If you are interested in learning more about conductive rubbers, shielding gaskets, or electro magnetic interference, contact a local manufacturer for more information. Shielding gaskets are a vital component that protects electronics from electromagnetic radiation and interference. If your business relies on the success of electronic components, make sure to familiarize yourself with shielding gaskets and the materials that allow them to function.
