Fabric Tape CN-4490 Series

Fabric Tape CN-4490 Series

3M fabric tape CN-4490 is a double-coated conductive, non-woven fabric and unique electrically conductive pressure-sensitive acrylic adhesive. CN-4490 tape is typically 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, shielded rooms, and more.

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, among others. This product has a 5-year shelf life from date of manufacture when stored in humidity-controlled storage (50°F/10°C to 80°F/27°C and 75% relative humidity).
