Fabric Tape CN-4190

3M™ Fabric Tape CN-4190 consists of copper-nickel coated conductive polyester

fabric and unique electrically conductive pressure-sensitive acrylic adhesive.

CN-4190 tape is typically used in many applications typically served by metal foil shielding

tapes such as grounding and EMI shielding equipment, components, shielded rooms, etc.

The unique fabric backing offers the additional benefits of excellent flexibility and

conformability, very light weight, and exceptional strength. The fabric backing also helps

minimize the possibility of finger lacerations.

Many factors determine the true shielding effectiveness of a shielding tape, including

type and thickness of foil adhesive type, intimacy of contact, smoothness of

application surface, strength and frequency of the EMI signal, etc. However, using

standard tests and fixtures, it is possible to determine a value for the attenuations.

For CN-4190 fabric tape, typical shielding effectiveness is in the range of 65dB to

70dB. Before using this product, the user must evaluate it and determine if it is

suitable for the intended application.
