Emi Conductive Fabric

Definition of EMI Conductive Fabric

EMI conductive fabric is a flexible shielding material produced by applying a metal coating through electroplating to insulating fiber fabric (primarily polyester fiber fabric) after pre-treatment, thereby imparting metallic conductivity. The metal coating reflects and attenuates electromagnetic waves while grounding and conducting them. Simultaneously, the flexible fiber fabric structure aids in absorbing certain low-frequency interference. This creates stable shielding performance across the 100KHz-3GHz frequency range, making it a classic material that balances shielding effectiveness with flexibility.

EMI conductive fabric’s parameter

Compared to traditional solutions like direct metal sealing and conductive coatings, the combination of EMI shielding gaskets and EMI conductive fabric offers significant advantages:

First, it provides superior flexibility. The conductive fabric adapts to complex structures and machining tolerances, while the gasket balances sealing and cushioning to prevent rigid impact damage common with metal seals.

Second, it offers high integration, with both components working synergistically to achieve electromagnetic shielding, environmental sealing (dust and water resistance), and shock absorption, simplifying equipment structural design.

Third, it provides high customizability, allowing adjustments to the conductive fabric coating and gasket structure based on size, frequency, and environmental requirements, accommodating all application scenarios from consumer electronics to defense equipment.
