Electrically Conductive

The products in our electrically conductive materials series have the superior qualities of silicone rubber, plus electrical conductivity thanks to the addition of carbon and other conductive materials. They are available in many forms, including sheets, tapes, O-rings and other desired shapes; and are ideal for electromagnetic shielding for office equipment and medical equipment, and as anti-static rubber for electric and electronic equipment.


Shin-Etsu Chemical’s EC-series exhibit superior electrically conductivity compared to synthetic rubbers in several ways:

EC series can be used for electromagnetic shielding, anti-static rubber, contact points, connectors, and an array of other application.
