  • 3M™ Shielding Non-woven Fabric Tape CN-4490

    Part Number CN-4490
    • Nickel on copper-plated polyester fabric backing provides corrosion resistance and good shielding effectiveness.
    • Polyester nonwoven fabric provides a very thin backing with excellent flexibility and conformability, mechanical strength, and light weight.
    • Polyester nonwoven fabric is also easily handled (minimizes finger laceration) and easily converted (slitting and die cutting).
    • Conductive particles in the adhesive on both sides provides low contact resistance between the substrate and backings to drain static charge.

    Additional Information
    The CN-4490 tape has conductive non-woven backing offers the additional benefits of excellent flexibility and conformability, very light weight, exceptional strength and resistant to oxidation, solvents and oils. The nonwoven backing also minimizes the possibility of finger laceration. Highly conductive particles in the acrylic adhesive provide a multitude of electrical paths between both sides the application substrate and the surface of the conductive non-woven backing. Acrylic adhesive has good resistance to heat, oxidation, solvents and oils. This tape is designed for a variety of applications: EMI/RFI shielding, grounding and static charge draining. These tapes can used in both electronic & electrical devices, shielding connectors & cables, shielded rooms and EMI test laboratories for prototyping, design and troubleshooting. The CN-4490 tape is available from 3M in log rolls (standard size of 19.7 inch x 109.4 yds or 500 mm x 100,0 m) to 3M slitter/converters. Also, 3M offers to 3M authorized distributors (and slitter/converters) various size slit rolls for resale to end users. Custom die-cut parts are available from 3M slitter/converters.
