Conductive gaskets are specialized sealing materials designed to provide electrical conductivity while also maintaining a physical barrier for environmental protection. They are typically used in applications where both electromagnetic interference (EMI) shielding and environmental sealing are required. These conductive seals prevent the leakage of electromagnetic waves (which can interfere with electronic components) and block external EMI from entering sensitive devices.
Key Characteristics
Conductive gaskets are often made of elastomers (like silicone or rubber) filled with conductive particles such as silver, nickel, or carbon. Some gaskets may also be made of metal mesh or fabric that is highly conductive.
Types of Conductive Gaskets
Elastomer-based gaskets: These are flexible and can accommodate irregular surfaces. The conductive fillers embedded in the elastomer allow it to conduct electricity while maintaining a seal.
Wire mesh gaskets: These are typically woven or knitted from metal wires like aluminum or copper. They provide excellent conductivity and EMI shielding.
Conductive fabric over foam: A foam core is wrapped with a conductive fabric, offering both flexibility and effective shielding.
Applications for Conductive Seals
EMI/RFI Shielding: Used in electronic enclosures, shielding sensitive electronics from radio frequency interference.
Sealing: Provide environmental protection against dust, moisture, and other contaminants.
Grounding: Can create a low-resistance electrical path for grounding electronic devices.
