Common conductive fabric tape for RFI/EMI (radio-frequency interference or electromagnetic interference) shielding and ESD (electrostatic discharge) grounding for components, integrated circuits, connectors, cables, motors, equipment enclosures/cabinets and shielded rooms.
Used in jobs requiring excellent conformability and flexibility while providing good shielding effectiveness.
Better than just copper plating for use in corrosive environments, as nickel on copper plating resists oxidation and corrosion.
The CN-3190 tape has conductive fabric backing offers the additional benefits of excellent flexibility and conformability, very light weight, exceptional strength and resistant to oxidation, solvents and oils. The fabric backing also minimizes the possibility of finger laceration. Highly conductive particles in the acrylic adhesive provide a multitude of electrical paths between the application substrate and the surface of the conductive fabric 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-3190 tape is available from 3M in log rolls (standard sizes of 19.7 inch x 21.8 yds or 500 mm x 20,0 m and 39.4 inch x 54.5 yds or 1000 mm x 50,0 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.
