Provides good RFI/EMI (radio-frequency interference or electromagnetic interference) shield with excellent ESD (electrostatic discharge) grounding for small consumer electronics (such as mobile handhelds, digital still cameras, liquid crystal display televisions, etc.), equipment enclosures/cabinets and shielded rooms.
Used as a conformable and flexible conductive gasket to bond both electrically and physically two shielded parts together, so as to form a complete RFI/EMI (radio-frequency interference or electromagnetic interference) shielded electronic enclosure with excellent ESD (electrostatic discharge) grounding.
The CN-4190 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 both sides 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-4190 tape is available from 3M in log rolls (standard size of 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.
