Electrically Conductive Silicone FAQs

What is electrically conductive silicone, and how does it provide EMI shielding and ESD protection?

Electrically conductive silicone is an engineered elastomer that blends silicone rubber with conductive filler particles (such as nickel-graphite, silver-plated aluminum, or carbon). This compound retains silicone’s signature flexibility and extreme temperature resistance while providing a continuous conductive path. This path allows the material to ground static charges (electrostatic discharge / ESD) and reflect or absorb high-frequency radiation to prevent electromagnetic interference (EMI) in sensitive electronic enclosures.

What filler materials are used in ElastaPro electrically conductive silicone sheets?

ElastaPro conductive silicones utilize high-performance filler particles customized for specific electrical performance and environmental conditions. Common filler systems include carbon-filled compounds for cost-effective ESD grounding and static dissipation, as well as metal-based or metal-coated particle fills (like nickel-graphite or silver-plated aluminum) designed to achieve low volume resistivity and high dB attenuation for demanding military, aerospace, and industrial EMI shielding requirements.

Can electrically conductive silicone sheets be supplied with pressure-sensitive adhesive (PSA)?

Yes. Conductive silicone sheeting can be backed with specialized pressure-sensitive adhesives to streamline gasket assembly and component placement. For applications requiring unbroken z-axis conductivity across the bond line, conductive pressure-sensitive adhesives are available. Non-conductive acrylic or silicone PSAs can also be applied in zones where structural adhesion is needed without disrupting the main conductive path.
