Fabric Tape CN-3490

3M™ 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.

grounding and EMI shielding equipment, components, shielded rooms, etc.

The unique and 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, etc.
