3M(TM) Nickel Copper-Coated Fabric Tape CN4490. Rolled back
3M™ Shielding Non-woven Fabric Tape CN-4490 has a thin 1.2-mil nickel copper-coated non-woven fabric backing with dual conductive pressure-sensitive adhesive and single liner.
Features and Benefits
  • 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.
  • Acrylic pressure-sensitive adhesive has good resistance to heat, oxidation, solvents and oils.
  • Removable liner makes it easy to handle and die cut complex shapes.
  • There are both standard and custom roll widths and lengths to meet a variety of application needs.
