Conductive Foam Shielding – Things That You Need To Know

Conductive Foam Shielding

With the advancement in the material used for shielding, electromagnetic waves of any range can be controlled easily. Whether it is a low or a high frequency wave, science has been successful in attenuating any form of radiations emitted from electronic devices. However, even after proper shielding, due to rough surfaces, leakage of radiation continues to create EMI. This is where gasket comes into play. Conductive foam shielding is one such innovative approach that offers X, Y, and Z-axis conductivity. It strengthens the shielding effectiveness without affecting the functionalities.


Conductive foam has been designed to control the electromagnetic radiations emitted from low-cycling applications like input/output shielding or rectangular strips,which are meant for gasketing applications. This conductive foam is basically made of polyurethane foam, plated with copper and nickel, compressed for 25-75 percent and at a temperature between 60 and 70 degrees Celsius. Once released, the foam returns to its normal height. The polyurethane feature protects the foam from environmental impacts.


Conductive foam has a low compression set that ensures long-term gasket performance. Compression of the conductive foam EMI gaskets depends upon the size of the gaskets. The material features low flammability characteristics. It has high workability due to adhesion and you can cut or slit it easily. Conductive foam can be used in mobile phones, noise filter cores, cable trays and shielded rooms.

This is a leading die-cut gasket perfect for any sized server, router, or switch system.Conductive foam is a cost-effective product that is used to shield various frequencies.
