3M™ CN3490

Overview for 3M™ CN3490

3M™ CN3490 is a nonwoven fabric shielding tape, consisting of a nickel copper-coated PET backing, with a conductive acrylic adhesive. The backing provides corrosion resistance and good shielding effectiveness.

It is a very thin, lightweight and mechanically strong tape, with excellent flexibility and conformability. The conductive particles in the adhesive provides low contact resistance between the substrate and the backing to drain static charge.

CN3490 tape is available in non-standard slit rolls, sheets and custom shapes. For more information, please contact us.
