3M™ Copper Foil Shielding Tape 1181 has a 1.4-mil smooth copper foil backing with a conductive acrylic pressure-sensitive adhesive and liner. The unplated copper with conductive adhesive is a common EMI shielding tape for non-corrosive conditions.
3M™ EMI Shielding Tape 1181 has a deadsoft, copper foil backing with a pressure sensitive, electrically conductive, acrylic adhesive that ensures firm adherence. The copper foil backing of the tape offers excellent resistance against oxidation and discoloration. 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. UL Listed and RoHS 2011/65/EU Compliant.
