1181 50MM

1181 50MM is a 3M™ EMI copper foil shielding tape 1181 with electrically conductive acrylic adhesive. It is a 2.6-mil thick tape composed of a 1.4-mil flat copper foil backing coated on one side with a non-corrosive, electrically conductive acrylic pressure-sensitive adhesive supplied on a removable liner. It is commonly used for EMI/RFI shielding applications in the electronics industry, static charge draining, seaming shielded rooms, cable wrapping, and surface contact with non-solderable materials. It can be die-cut, is solderable and offers a multitude of uses in electrical design and test laboratories for prototyping, design and troubleshooting. It is designed for applications that require reliable, point to point electrical contact. The conductive particles in the adhesive offer low resistance between the substrate and the backing. This flame-retardant tape is designed for grounding and EMI shielding in equipment, components and shielded rooms.
