Description
Applications
3M™ Fabric Tape CN-3190 consists of anti-corrosion polyester rip-stop fabric and
unique electrically conductive pressure-sensitive acrylic adhesive.
3M CN-3190 is used in applications typically served by metal foil shielding tapes such as
grounding and EMI shielding equipment, components, shielded rooms, etc.
The unique metal-plated fabric backing offers the additional benefits of excellent flexibility
and conformability, very light weight, and exceptional strength. The fabric backing also
minimizes the possibility of finger lacerations.
Shielding
Effectiveness
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, etc. However, using
standard tests and fixtures it is possible to determine a value for the attenuations. For
CN-3190 fabric tape, typical shielding effectiveness is in the range of 65dB to 70dB.
Before using this product, the user must evaluate it and determine if it is suitable for
the intended application.
