TG-FAM flexible absorbent material EMI Shielding

What is EMI Shielding?

EMI shielding is the process of reducing or preventing electromagnetic interference with electronic devices. This can be achieved by using materials that are able to absorb or reflect electromagnetic waves.

These materials are typically made of a combination of conductive and non-conductive materials and have the ability to absorb electromagnetic waves by converting the energy into heat. Some examples of flexible absorbent materials include copper-coated nylon, copper-coated polyester, and nickel-coated polyester.

EMI Shielding materials are usually applied as a coating or a layer that is integrated into the device or equipment that requires shielding from electromagnetic interference. For example, they can be integrated into enclosures, cables, and gaskets. Due to their flexible nature, these materials can be used in applications where traditional rigid materials may not be suitable, like in flexible devices.

Flexible absorbent materials can be used to shield against a wide range of frequencies, including both high-frequency (HF) and low-frequency (LF) electromagnetic waves. They are also effective at reducing electromagnetic interference caused by both internal and external sources.

When selecting flexible absorbent materials for EMI shielding, it’s important to consider the specific requirements of the application. Factors such as the frequency range, the level of shielding required, the operating temperature range, and the mechanical properties of the material need to be considered.

T-Global Technology offers EMI shielding with its TG-FAM series of flexible absorbent materials. Our ultra-thin FAM series offers effective EMI suppression across a wide frequency and working temperature range. Our flexible absorbent materials provide high surface resistance and are made from magnetic particles and rubber or a sintering iron core and can be supplied with a non-conductive adhesive backing if required.
