EMI Shielding Gaskets
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 shields, foam tapes and 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 for tensile strength, tear resistance and thermal stability/conductivity.
Particle-filled silicones offer the performance characteristics of silicone with the electrical properties of metals. They can contain aluminum, copper, graphite, nickel or silver. EMI shielding gaskets don’t just inhibit electrical and radio frequency interference (RFI); they also withstand abrasion, chemicals and extreme temperatures.
- Voltage endurance
- Thermal conductivity
- Excellent dielectric strength
- Mechanical toughness

As you develop products that need EMI or RFI protection, ask these questions.
Gasket functionDo 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?
Gasket sizeAre there limitations on gasket format (die cut vs. stripping)?
Gap spacingWhat is the thickness range of the gap?
TemperatureWhat high and low temperatures will the material reach and for how long?
UV/Ozone resistanceWill the material be directly exposed to the elements?
Flame ratingDoes your application include requirements like UL-V0, UL-HBF or FMVSS-302?
Chemical resistanceWill the material be in contact with chemicals or fluids?
OutgassingCould material outgassing be detrimental to components?
ColorWill a particular color improve ease of assembly or help with future inspections?
Cost and performanceDoes your application require a premium product?
