Description  

Applications  

3M™ Fabric

T

a

pe 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.
