EMI Shielding Silicone Extrusion Profiles

Inclusive of all taxes

Our EMI Shielding Silicone Extrusion Profiles are high-performance elastomeric compounds designed to provide superior electromagnetic interference (EMI) protection for sensitive electronic devices and circuits. These profiles incorporate conductive fillers such as nickel-graphite, silver-aluminum, or silver-coated copper particles within a silicone matrix, enabling excellent electrical conductivity. The materials effectively reflect and absorb electromagnetic waves, preventing signal disruption in electronic systems. Engineered for versatility, these extruded profiles maintain stability across a broad temperature range (-60°C to +230°C), possess outstanding mechanical flexibility to endure repetitive stresses without losing shielding capabilities, and exhibit strong resistance to environmental factors including UV radiation, ozone, and aggressive chemicals. Available in customizable shapes and sizes, the EMI Shielding Silicone Extrusion Profiles are ideal for OEMs and electronic manufacturers needing tailored solutions for EMI mitigation in harsh or demanding environments.
