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. Features dead-soft 1-ounce copper foil backing for good shielding effectiveness, soldering and converting (slitting and die-cutting). UL recognised flame-retardancy per UL 510 for applications needing this property. Conductive particles in the adhesive provides low contact resistance between the substrate and the backing to drain static charge. Acrylic pressure-sensitive adhesive has good resistance to heat, oxidisation, solvents and oils. Removable liner makes it easy to handle and die cut complex shapes.
