Conductive Foam Shielding Material

With advancements in shielding material, electromagnetic waves of any range can be easily controlled. Science has been successful in attenuating any type of radiation emitted by electronic devices, whether it is a low or high frequency wave. However, even after proper shielding, radiation leakage causes EMI due to rough surfaces. This is where the gasket comes in. Conductive foam shielding is one such innovative approach that provides conductivity along the X, Y, and Z axes. It improves shielding effectiveness without impairing functionality.

Features
Conductive foam was developed to control electromagnetic radiations emitted by low-cycling applications such as input/output shielding or rectangular strips used for gasketing. 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.
