RFI and EMI shielding and absorbing materials serve the purpose of limiting the interference caused by the emission of Radio Frequency Interference (RFI) and Electro-Magnetic Interference (EMI). Different materials such as metal, fabric, foam and other materials are employed with the purpose of reducing or eliminating interference. As a result, the performance and stability of any electronic equipment is improved, and reliability increases.

3M AB5050 CIRCLE-0.875" - 250 is one particular type of material which performs the dual roles of shielding and absorbing electromagnetic radiation. It is classified as a highly absorbent conductive foam, and is made from a blend of polymeric foam, copper particles and carbon particles. The product is designed for use in electrical components which are susceptible to EMI/RFI interference. The standard size is 0.875" with a thickness of 250 mil.

The way in which 3M AB5050 CIRCLE-0.875" - 250 works as an absorber of electromagnetic interference is by utilising a combination of unique materials and a conductive matrix. The conductive matrix consists of a combination of the copper and carbon particles which are evenly distributed throughout the foam material. This fine layer of conductive particles ensures that a large portion of the electromagnetic wave is absorbed by the foam. The combination of the copper and carbon particles also ensures that the absorber does not suffer from outgassing or moisture absorption.

In addition to acting as an absorber, 3M AB5050 CIRCLE-0.875" - 250 also serves as a shielding material. The special combination of the copper and carbon particles in the material is designed to provide an effective shield against unwanted interference. The conductive particles in the layer block out any incoming EMI/RFI interference, ensuring that the electrical component or device which it is covering is protected against interference.

3M AB5050 CIRCLE-0.875" - 250 is also highly durable and resistant to water and temperature changes, making it ideal for use in a variety of fields such as telecommunications, aerospace, defence and automotive applications. It is also easy to install and can be quickly and easily applied using common adhesives. In addition, the material can easily be cut and trimmed to fit the exact size and shape of any electrical component or device.

In conclusion, 3M AB5050 CIRCLE-0.875" - 250 is an ideal material when it comes to shielding and absorbing EMI/RFI interference. It is made from a combination of specialised materials which allow it to effectively absorb as much of the interference as possible while also providing an effective shield against the incoming interference. In addition, the material is easy to install, durable and resistant to water and temperature changes, making it suitable for use in a wide range of applications.
