3M™ Flux Field Directional Material (FFDM) EM25TP

Product Description

3M™ Flux Field Directional Material (FFDM) EM25TP is a composite material consisting of a carrier resin, magnetic fillers and

an optional acrylic pressure sensitive adhesive (PSA) and optional Black PET top film layer. This magnetic material is

designed to interact and influence an Electro-Magnetic (EM) field. The EM field could be generated for various reasons

and in many applications it is desired to focus the EM field across a specific volumetric area, such as a secondary EM

field pick-up coil or antenna in a frequency range of below 5-10 MHz typically.

The 3M FFDM EM25TP uses in the frequency range above the 5-10 MHz range is typically as an EMI EM field absorber

as the higher loss (u”) characteristics of the 3M FFDM EM25TP provide for excellent EM field reduction.

3M FFDM EM25TP is designed to efficiently couple to the EM field and redirect and focus the field as desired in a given

application or to provide EM absorbing.
