3M Copper Foil Tape 1181
At NEDC, we work with many materials that are used for EMI/RFI shielding, including gaskets, seals, and extrusions. While gaskets are our core product line, we also provide the value added benefit of converting 3M Copper Foil Tapes. 3M provides various different foil tapes, but this blog will cover one of the more common types NEDC works with: Copper Foil.
Uses/Properties of 3M Copper Foil Tape
In a world that is becoming more focused on electronics by the hour, 3M provides a adhesive copper tape that can provide great shielding effectiveness, and conductivity for EMI shielding. These tapes are used to reflect, attenuate, and block signals coming from the outside environment. Not only do they attenuate signals from the outside, they can also provide shielding from other components inside the assembly. These tapes have been used for a number of shielding applications, including shielded rooms, enclosures, reduction in electrostatic coupling, and other grounding applications, while providing an effective, and economical means to do this. In addition, the tapes have a reliable way to remove dangerous static charges through high conductivity. Most of 3M’s Copper Foil Tapes are provided with an electrically conductive adhesive to ensure complete electrical contact even through/at the bond area.
Types/Adhesives Available for Conductive Foil Copper Tape
There are many constructions of foil tape available. Some foil tapes have an embossed pattern, such as 3M1245. This embossed pattern is important because it is able to penetrate spots in the adhesive, conductive or nonconductive, to provide an electrical contact. 3M Copper Foil Tapes are provided with acrylic adhesives that can provide high strength bonding to high surface energy substrates such as aluminum or steel, substrates typical in electrical enclosures. These tapes can also show resistance to temperature, and aging. There are times that it is necessary to stick the copper foil to two different substrates simultaneously, and in cases such as these the 3M1182 Copper Foil may come in handy. This tape is equipped with conductive acrylic adhesive on both sides of the foil, providing strong adhesion on both sides. The only copper foil without electrically conductive adhesive is 3M1194. However, all of the copper foil backings maintain a low resistivity to ensure high conductivity. All of these tapes are UL-recognized under UL 510 for flame retardancy.

Why Chose 3M Copper Foil Tape over other Competitive Brands?
To us, this choice is simple. 3M Copper Foil Tapes are tried, and true. Since NEDC is a 3M Converter, NEDC has been using 3M Copper Foil Tapes for over 30 years to provide custom die-cut shapes to customers for many different types of applications. Another reason to use 3M, is although these tapes have been tested in applications extensively, they have the objective testing to back it up, such as different Underwriters Laboratorties testing, recognitions as UL 510(flame retardancy), or for example EMI shielding testing such as MIL-STD-202 Method 307.
More Information/Cutting for Copper Foil Adhesive Tapes
As an authorized 3M converter, NEDC can supply diecut parts or rolls. These tapes can also be provided on a liner for ease of removal by being “kisscut” which can be provided with, or without the copper foil webbing still intact.
