3M™ EMI/EMC Materials
Solutions for protecting electronics from the effects of
electromagnetic interference and electrostatic discharge
Safeguard your designs with
3M™ EMI/EMC Materials
Generated from common electronics and communications signals,
thunderstorms and solar activity, electromagnetic frequencies and
static electricity are part of everyday life. Though they are almost
always present, these phenomena can interfere with electronic device
performance, potentially causing errors or data loss.
Reduce interference – and help protect your customers’ investments
– by incorporating 3M™ EMI/EMC Materials into your products.
These solutions block and/or absorb electromagnetic interference
(EMI) from a wide variety of frequencies and sources to help
keep electronics performing at their full potential. Complementing
our EMI/EMC solutions, 3M offers Flux Field Directional Materials
(FFDM) that are useful for magnetic shielding, wireless power
charging and near field communications (NFC).
Excellent
versatility
Our 3M™ EMI/EMC
Materials are highly
versatile and appropriate
for diverse applications:
• Consumer electronics
• Servers and high
performance computing
equipment
• Communications
infrastructure
• Defense electronics
• Automotive electronics
Don’t let unwanted frequencies

Solutions for NFC, WPC
and magnetic shielding
Near field communication (NFC), radio frequency
identification (RFID) and wireless power charging
(WPC) antennas often face unique interference
challenges and can be optimized for performance
using Flux Field Directional Material (FFDM)
solutions. These low profile solutions can help improve
WPC efficiency and NFC or RFID read ranges.
3M FFDM solutions can also be used for magnetic
field shielding to help protect sensitive electronics.
• 3M™ Flux Field Directional Materials are thin, with high
magnetic permeability and low magnetic loss that help
provide efficient flux field redirection for applications
less than 20 MHz. Three different types of FFDMs are
available from 3M:
o Composite, for maximum flexibility
and lower cost
o Ferrite, for high performance across
broad frequencies
o Nano-crystalline metal foil, for a thinner
profile and high performance across
low frequencies
Solutions for EMI absorption
Another way to protect electronics from EMI
interference is to absorb the frequencies using
materials incorporating specialized magnetic particles.
Whether your application requires absorption of low or
high frequencies, we have a 3M™ EMI Absorber with
high performance in one or more of the key frequency
ranges: 0.1-1.0 GHz, 1-6 GHz and greater than 6 GHz.
• 3M™ EMI Absorbers are designed to work to dissipate
and absorb EMI at most common frequencies. High
and low frequency options are available, and there are
multiple thicknesses available to suit diverse
applications. These materials are flexible and
offer high permeability and magnetic loss in the
targeted frequency range.
• 3M™ EMI Shielding Absorbers offer the benefits of
EMI shielding and absorption together in one product
for maximum protection. This solution includes an
EMI absorber and an aluminum shielding layer plus an
optional conductive adhesive for added grounding.
All-around solutions for tough EMI/EMC challenges
Solutions for shielding and grounding
Your designs require robust protection against EMI
interference and electrostatic discharge (ESD) and our family
of solutions for shielding and grounding can help. All are
designed to be lightweight and require less space while
delivering high conductivity and reliability.

Electrically Conductive Adhesive Transfer Tapes
are designed to deliver a broad spectrum of performance
including products with high EMI shielding in the bond
line gap for high frequency attenuation, stable contact
resistance and reliable electrical conductivity. Multiple
thicknesses are available, including double-coated, non-
woven and particle designs.
• 3M™ EMI Foil and Fabric Tapes offer shielding
against a wide range of EMI frequencies. They
are available in conductive fabric and foil backing
options, and multi-layer laminate options (including
PET, polymer films and foil) that offer increased
toughness and external electrical insulation.
• 3M™ Electrically Conductive Cushioning Gasket
Tapes are soft, conformable foam that adhere well
to a wide variety of surfaces. They provide excellent
electrical conductivity, EMI shielding and grounding.
