Conductive Silicone Foam in EMI Shielding for Industrial Communication Equipment | Konlida

2025-08-18

Introduction

With the rapid expansion of 5G networks and industrial communication systems, the demand for reliable electromagnetic interference (EMI) shielding materials is growing. Among the many solutions available, conductive silicone foam stands out for its combination of excellent conductivity, compressibility, and environmental stability. This makes it a preferred choice for critical equipment such as 5G base stations, routers, and industrial communication modules.

Key Properties of Conductive Silicone Foam

Conductive silicone foam is engineered to maintain stable shielding performance even under harsh environmental conditions such as temperature fluctuations, humidity, and mechanical stress. Its advantages include:

High conductivity – ensures effective EMI shielding across a broad frequency range.
Excellent compression set resistance – allows repeated assembly and disassembly without performance loss.
Durability in extreme environments – maintains stable function in outdoor or high-temperature applications.
Environmental compliance – Konlida’s formulations are RoHS and REACH compliant, supporting sustainability goals.

Compared to traditional conductive foams, conductive silicone foam provides superior sealing and weather resistance, making it ideal for outdoor communication equipment.
