A common question people ask is: can rubber conduct electricity? The answer depends on the material that is being used. If the rubber material does not contain any conducting electrons, then it will not conduct electricity. Rubber is known to be an insulator because rubber can limit the transfer of electricity. The rubber properties prevent the electrons to be able to freely move and the addition of the electrons being tightly bounded makes rubber a good insulator . Furthermore, rubber itself usually cannot conduct electricity without any assistance.<\/p>\n

Rubber as a conductor<\/a><\/strong><\/h3>\n

As a conductor rubber are poor conduits of electricity hence the reason you see electricians wear rubber gloves when they are working with electric wires. This does not guarantee that the person does not get electrocuted because if there is strong enough of voltage then that object may still conduct electricity such as power lines. Another method that rubber becomes a conductor is if the rubber material gets wet and may pose a risk to the person touching the wet rubber.\u00a0 In addition, if you have a rubber that has additives such as carbon or metallic additives mixed with it then it may have electrical properties.<\/p>\n

Example of a conductive additive that is extremely additive is single-wall carbon nanotubes. Single wall carbon nanotubes are known to be a nanofiller with properties such as 6 orders of magnitudes higher than copper and high current carrying capacity making SWCTN\u2019s a remarkable source for electrical conductivity.\u00a0Single wall carbon nanotubes\u00a0 can also provide the advantage of improving elastomer properties<\/a> such as tensile strength, making the material able to withstand heavier mechanical loads according to research from Nanowerk(https:\/\/www.nanowerk.com\/nanotechnology-news\/newsid=39408.php).<\/p>\n

What is Conductive Rubber?<\/b><\/h3>\n

Definition: Conductive Rubber is a generic term referring to any rubberized material with conductive properties which reduce or eliminate the EMI\/RFI (electromagnetic interference and radio frequency interference) \u201cnoise\u201d that is often associated with electronics.<\/p>\n

 <\/p>\n

Multicon material is one of the most prevalently used forms of conductive rubber today. It\u2019s a combination of silicone and conductive wire paths which provides a superior environmental seal while providing EMI\/RFI shielding to frequencies up to 6 GHz.<\/p>\n

Multicon is offered in either solid or sponge silicone with either monel or aluminum wires for conductivity. The conductive wires are dispersed throughout the width of the material to provide great protection against EMI\/RFI contamination. It\u2019s constructed in such a way that when pressure is applied to the gasket, hundreds of sharp wire ends become exposed making electrical contact with mounting surfaces.<\/p>\n

Multicon can be provided in a wide range of thicknesses and widths to meet the needs of a specific application, or the material can be die-cut to meet various configurations.<\/p>\n
