Technical Data Sheet

3M™ Electrically Conductive Gasket Tape MSG7250SDX is a highly compressible, electrically conductive gasket tape constructed from Cu/Ni-plated polyurethane foam laminated to a conductive fabric for excellent conformability and mechanical stability. It features a transparent conductive acrylic pressure-sensitive adhesive (CPSA) that provides strong adhesion and high EMI shielding effectiveness, even through adhesive bond lines. By combining conductive foam, fabric, and adhesive in a single material, MSG7250SDX delivers consistent and reliable conductivity in dense or complex electronic assemblies, offering excellent grounding performance between substrates, high EMI shielding effectiveness, and very low contact resistance, even at small die-cut sizes. It is ideal for applications requiring highly reliable conductive connections, ESD grounding, conductive enclosure sealing for superior EMI shielding, and designs with small gasket geometries and large gap tolerances.

The 3M™ MSG7000SDX Series is available in 9 thicknesses ranging from 0.3 mm to 3 mm.
