Non-Woven Conductive Fabric Tape

CN-3490 is a non-woven conductive fabric tape from 3M™

Image of 3M's Non-Woven Conductive Fabric Tape3M Fabric Tape CN-3490 is a conductive, non-woven fabric and unique electrically-conductive, pressure-sensitive acrylic adhesive.

CN-3490 tape is used for applications requiring excellent electrical conductivity from the substrate, through the adhesive, to the conductive backing. Common uses include grounding and EMI shielding equipment, components, and shielded rooms. The unique, thin metallized backing offers the additional benefits of excellent flexibility and conformability, very light weight, and exceptional strength. The conductive 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.
