EMI Shielding Gaskets

Custom gaskets protect components against electromagnetic interference (EMI)

EMI shielding gaskets protect electronic devices and components from electromagnetic interference (EMI) and radio frequency interference (RFI)

Power supplies, motors and other energy sources can generate unwanted electromagnetic signals that interfere with the functions of critical electronic devices and components. This creates a technical challenge for many OEMs that incorporate electronics in their products.

We convert materials such as particle-filled silicone into EMI shielding solutions for electronic devices, helping guard against device malfunction or failure. We can custom fabricate them to your exact specifications and requirements.

Features and Benefits of EMI Shielding Gaskets

Sealing against conducted or radiated EMI that can interfere with circuits

Flurosilicone EMI materials offer greater resistance to fuel, oil, and other chemicals

EMI silicone materials can meet military, UL and ASTM standards

Silicone provides broad temperature resistance and is a thermal insulator that can resist thermal cycling between temperature extremes

EMI silicones are available in a range of hardnesses, including lower durometers for gaskets where there is less closure force

These materials are easy to die-cut, fabricate into custom gaskets, and can be supplied with a PSA backing

BISCO® Silicone EC-2130

BISCO^® EC-2130 is a soft electrically conductive silicone used to reduce EMI and RFI to protect critical electrical components. Its combination of extra soft polymer and highly conductive filler creates an environmental seal. BISCO EC-2130 electromagnetic shield conductive silicones reduce EMI and RFI at frequencies above 10 GHz in a wide range of electronic applications.

SSP EMI / RFI Conductive Silicones

SSP supplies a full line of EMI / RFI shielding materials as compression-molded sheet stock, and as continuous rolls. In this way, SRP can convert SSP’s conductive silicones into shielding gaskets via the most efficient, cost-effective method.

Key Features

Fluorosilicones combine the high and low-temperature resistance of silicones with the fuel and oil resistance of fluorocarbons.
Compounds that are filled with metal or metal-coated particles also provide electrical conductivity and EMI shielding.
3B Certified Silicones With High Flex-Fatigue Resistance.
Materials to meet a variety of gasket standards.

Benefits

SSP supplies various fluorosilicone formulations to meet the following specs:

MIL-DTL-83528
UL 94 V0
UL 50-E
ASTM B117
ASTM E595

Applications

Automotive
Aerospace
Satellite Communication
Unmanned Systems
Electronic Devices

Design

As you develop products that need EMI or RFI protection, ask these questions.

Gasket function

Do you need the gasket to do more than block EMI or RFI, such as sealing out liquids, solids or air, or mitigating shock or vibration?

Gap spacing

What is the thickness range of the gap?

Temperature

What high and low temperatures will the material reach and for how long?

Flame rating

Does your application include requirements like UL-V0, UL-HBF or FMVSS-302?

Chemical resistance

Will the material be in contact with chemicals or fluids?

Cost and performance

Does your application require a premium product?
