Applications
3M Tape 2191FR can be used in many applications
such as grounding and EMI shielding in equipment,
components, shielded rooms, etc. The unique
metallized 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
laceration.
Shielding Effectiveness
Shielding effectiveness depends on conductivity,
permeability, thickness of metalization, adhesive
strength, degree of contact, smoothness of
application surface, strength and frequency of EMI
signal, etc. However, using standard tests and
fixtures, it is possible to determine a value for the
attenuation. (See chart below.)
