EMI Shielding Materials – What’s Best for Your Application?

There are a few common materials used to shield electromagnetic interference: foil, metallized cloth, and metal mesh. These materials come with their own advantages and disadvantages, we will explore their main characteristics below:

Mesh Highly flexible Heavier compared to fabric and foil Excellent low frequency attenuation Lower attenuation at high frequencies Higher cost

Cloth Highly flexible Light weight Excellent attenuation across low and high frequencies Permeable and can absorb fluids

Foil Flexible Superior attenuation, especially at high frequencies Not suitable for applications with repeated flexing Low cost

Knowing the attributes of each material type will aid in determining which material is the best fit for your unique application. Zippertubing can work with you to determine the best material and closure combination for a successful and long-lasting EMI Shielding Solutions.
