Conductive Silicone Material

conductive siliconeConductive Silicone – General Description

MAJR Products’ Conductive Silicone is a molded silicone filled with conductive inert particles. It provides high electrical conductivity, broadband shielding and moisture sealing.

Conductive Silicone are manufactured in sheets, extrusions, strips and custom molded parts.

Application Information

Conductive Silicone should be used where there is a need for high broadband shielding with excellent moisture sealing. In order to assure electrical conductive and sealing reliability, recommended design compression is 7% – 15% of original height for sheets and strips and 12%-30% for hollow profiles.
