3M 1181

3M 1181 is a 2.6-mil (0.066 mm) thick tape composed of a 1.4-mil (0.036 mm) flat copper foil backing coated on one side with a non-corrosive, electrically conductive acrylic pressure-sensitive adhesive supplied on a removable liner.

  • Color: Copper
  • Thickness: 2.6-mil (0.066 mm)
  • Backing: Copper Foil - Flat
  • Adhesive: Electrically Conductive Acrylic
  • 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 provide low contact resistance between the substrate and the backing to drain static charge
  • The acrylic pressure-sensitive adhesive has good resistance to heat, oxidation, solvents, and oils
  • The 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

3M 1181 Features

  • Can be die-cut, is solderable, and offers a multitude of uses in electrical design and testing.
  • laboratories for prototyping, design, and troubleshooting.
  • The adhesive requires no moisture, solvents, heat, or other manner of preparation to affect the application.
  • Flame Retardant per UL-510A Standard.
  • The unplated copper with conductive adhesive is a common EMI shielding tape for non-corrosive conditions.
  • Highly conductive particles in the acrylic adhesive provide a multitude of electrical paths between the application substrate and the surface of the copper foil.
  • The acrylic adhesive has good resistance to heat, oxidation, solvents, and oils.

3M 1181 Applications

  • Commonly used for EMI/RFI shielding applications in the electronics industry and for static charge draining, seaming shielded rooms, cable wrapping, and surface contact to non-solderable materials.
  • This tape is designed for a variety of applications: point-to-point electrical contact, EMI/RFI shielding, grounding, and static charge draining.
  • These tapes can be used in both electronic & electrical devices, shielded rooms, and EMI test laboratories for prototyping, design, and troubleshooting.
