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 and Benefits
  • Dead soft 1-ounce (1.4-mil) copper foil backing for good shielding effectiveness, soldering and converting (slitting and die cutting).
  • UL recognized 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, oxidation, solvents and oils.
  • Removable liner makes it easy to handle and die cut complex shapes.
  • There are both standard and custom roll widths and lengths to meet a variety of application needs.
