Electrically Conductive Silicone Gasket
Electrically Conductive Silicone Gasket Supplier
Electrically conductive silicone rubber gaskets are specialized sealing components designed to provide environmental sealing while maintaining electrical conductivity between mating surfaces. These gaskets are commonly used in electronic equipment, communication devices, and industrial systems where EMI shielding, grounding, or electrostatic discharge protection is required.
Suconvey manufactures custom electrically conductive silicone rubber gaskets engineered for reliable electrical performance, environmental resistance, and mechanical durability. Our conductive silicone sealing solutions are widely used in electronics housings, control panels, communication equipment, and other sensitive electronic assemblies.
Electrically Conductive Silicone Gasket
An electrically conductive silicone rubber gasket is an elastomer sealing element produced by combining silicone rubber with conductive fillers such as carbon black, silver-coated particles, or nickel-coated graphite. These fillers create conductive pathways within the silicone matrix, allowing the material to conduct electricity while maintaining flexibility and sealing capability.
Unlike traditional silicone gaskets that function purely as insulators, conductive silicone gaskets provide:
Electrical conductivity
EMI/RFI shielding capability
Static discharge protection
Environmental sealing
This combination makes them an ideal material for modern electronic and electromagnetic compatibility (EMC) applications.

Key Performance Advantages
Electrical Conductivity
Conductive silicone rubber typically exhibits resistivity ranging from 10³ to 10⁻³ ohm·cm depending on filler type and concentration, allowing it to transmit electrical current while retaining elastomer flexibility.
EMI & RFI Shielding
Electrically conductive elastomers are widely used for electromagnetic interference shielding in electronic housings, preventing unwanted electromagnetic emissions and protecting device performance.
Wide Temperature Resistance
Silicone elastomers maintain stable performance across wide temperature ranges, typically from -55°C to 200°C, even under vibration and harsh environmental conditions.
Flexibility & Durability
Unlike metal EMI gaskets, conductive silicone gaskets provide:
- excellent elasticity
- corrosion resistance
- long-term mechanical durability
