PREFORMED EMI/RFI SHIELDING COMPOSITION IN SHAPED FORM

摘要

PROBLEM TO BE SOLVED: To provide an electrically conductive preformed composition. SOLUTION: The electrically conductive preformed composition comprising a sulfur-containing polymer in shaped form and the use of the preformed composition in shaped form to seal an aperture are disclosed. The preformed composition can be used to seal an aperture having EMI/RFI shielding effectiveness. The sulfur-containing polymer is present in an amount ranging from 10 to 50 wt.% of the total weight of a base composition. The sulfur-containing polymer is chosen from a polysulfide polymer, mercapto-terminated polymer, and a combination of a polysulfide polymer and a mercapto-terminated polymer.
