General Descriptions
MAJR Products’ Conductive Elastomer (5000 series) is a molded elastomer filled with conductive inert particles. It provides high electrical conductivity, broadband shielding and moisture sealing.
Conductive Elastomers are manufactured in sheets, molded parts, strips and die-cut flat gaskets.
Application Information
Conductive Elastomers 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.
