EMI & RFI Shielding Materials
In an increasingly connected world, electromagnetic interference (EMI) and radio-frequency interference (RFI) can disrupt the functionality of electronic devices and systems. EMI & RFI shielding materials are designed to mitigate these interferences, ensuring electromagnetic compatibility (EMC). In this web page, we will explore the significance of EMI & RFI shielding materials, common application considerations, and discuss different types used in various industries.
The CanGuard™ line of materials, O-rings, gaskets, & custom molded parts are at the leading edge of shielding polymer technology. Proven in the field year after year, CanGuard™ materials O-rings, gaskets, & custom molded parts have been developed to offer superior sealing solutions with enhanced electromagnetic interference (EMI) shielding and radio frequency interference (RFI) shielding.

EMI & RFI Shielding Materials Available
Thousands of EMI & RFI Shielding Materials are available now with Canyon Components! Some common EMI & RFI Shielding Materials include the following.
What are EMI & RFI Shielding Materials?
- EMI & RFI shielding materials are substances, coatings, or components engineered to block or absorb electromagnetic and radio-frequency signals, preventing unwanted interference with electronic devices. These materials are critical for maintaining the reliability and performance of sensitive electronic systems.
Common Conciderations
- 1. Frequency Range
Materials must be selected based on the specific frequency range of the interference to be shielded. Different materials are effective at different frequencies.
2. Shielding Effectiveness
The shielding effectiveness of materials, measured in decibels (dB), determines their ability to attenuate or block electromagnetic and radio-frequency signals.
3. Material Form
EMI & RFI shielding materials are available in various forms, including specialty elastomer blends, foils, conductive paints, gaskets, and enclosures. The choice depends on the application and installation requirements.
4. Environmental Conditions
Consider the environmental conditions, such as temperature, humidity, and exposure to chemicals, to ensure that the selected materials remain effective over time.
5. Regulatory Compliance
Materials should comply with industry standards and regulations, such as MIL-DTL-83528 for military applications or FCC regulations for consumer electronics.
6. Integration with Design
The integration of shielding materials into the design of electronic devices or enclosures is crucial to achieving optimal EMI & RFI performance.
Material Options
- 1. Conductive Gaskets and Seals
Conductive gaskets and seals are used to create a conductive seal between mating surfaces, providing EMI & RFI protection in enclosures.
2. Conductive Foils
Conductive foils made of materials like copper or aluminum are used to create effective shields within enclosures or on the surfaces of electronic devices.
3. Conductive Paints and Coatings
Conductive paints and coatings contain metallic particles and can be applied directly to surfaces to create shielding layers.
4. Conductive Fabrics and Tapes
Conductive fabrics and tapes are flexible materials that can be used to wrap or cover sensitive components or cables.
5. Shielded Enclosures
Entire enclosures can be designed to act as shields, offering complete protection for electronic equipment.
