3M™ CN4490

Overview for 3M™ CN4490

3M™ CN4490 is a nonwoven fabric shielding tape, consisting of a nickel copper-coated PET fabric, with dual conductive pressure-sensitive adhesive and single liner. The unique and thin metallised backing offers the additional benefits of excellent flexibility and conformability and exceptional strength. The conductive particles in the adhesive on both sides provides low contact resistance between the substrate and backings to drain static charge.

CU4490 is available in non-standard slit rollls, sheets and custom shapes. For more information, please contact us.
