The Conductive Silicone Foam is a functional material designed for highly static-sensitive and EMI shielding applications.
Manufactured through a composite foaming process of conductive fillers and liquid silicone, it features an extremely low surface resistivity (10²–10⁵ Ω), allowing for rapid static charge dissipation and effective electromagnetic interference (EMI) suppression.
Combining excellent conductivity, flexibility, compression resilience, and environmental stability, it is widely used in industries requiring stringent ESD protection and EMI compatibility.
Static Control Mechanism
SENMA’s Conductive Silicone Foam incorporates a uniformly dispersed conductive filler network, ensuring consistent and predictable electrostatic discharge (ESD) performance. It offers a surface resistivity range of 10³–10⁵ Ω/sq, making it highly effective for applications requiring rapid static dissipation while maintaining low electrical resistance. Unlike coated or surface-modified alternatives, its bulk conductivity remains stable over time, unaffected by surface wear, abrasion, or cleaning processes. Compliant with ANSI/ESD S20.20 and IEC 61340-5-1 standards, it delivers reliable static protection for highly sensitive electronic components without introducing significant current leakage.
Multi-Layer Protection
Efficient Static Dissipation: Provides immediate discharge paths for high-sensitivity components such as PCBs, ICs, and RF devices.
Resilient Cushioning: Closed-cell silicone structure ensures excellent shock absorption, dust resistance, and protection against moisture and chemicals.
Thermal Resilience: Operates reliably across a temperature range of –60°C to +200°C while retaining elasticity and low compression set.
Cleanroom-Safe: Ultra-low particle release, halogen-free, and compliant with ISO Class 3-5 cleanroom requirements.
