It is well-known that RFI (Radio Frequency Interference) and EMI (Electro Magnetic Interference) are two common forms of noise that can affect the performance of electronic equipment. One of the best solutions to minimising these disturbances is to use shielding and absorbing materials. We are going to take a closer look at one specific material, 3M AB5020HF 1.5”CIRCLE-25, and its application field and working principles.

3M AB5020HF 1.5”CIRCLE-25 is a cellular polypropylene foam shielding material. It is composed of wrapped cells, which are capable of absorbing and deflecting noise depending on its frequency. Specifically, the material offers superior protection against EMI and RFI. It is suitable for both indoor and outdoor application, and it is designed with corrosion resistance and flame retardance properties. In addition, it also exhibits good mechanical properties such as strength, flexibility and durability.

One of the main advantages of using 3M AB5020HF 1.5”CIRCLE-25 shielding material is that it is easy to install. The material can be rolled or die-cut to the required shape. Additionally, it is suitable for use in high-temperature and high-humidity environments. The material is also highly resistant to water and oil, and it is recyclable. In terms of performance, the material provides an excellent attenuates level, which is up to 90% for both EMI/RFI and ESD (Electro Static Discharge).

Aside from those mentioned above, another application field for 3M AB5020HF 1.5”CIRCLE-25 is for RF shielding. This material is often used for enclosures and devices which are susceptible to high levels of RF energy. In order to be effective, shielding blocks require a high level of conductivity which the material offers. The material has excellent conductive properties in which it can act as an effective shield against EMI and RFI.

3M AB5020HF 1.5”CIRCLE-25 is also widely used as a noise barrier in industrial and commercial settings. Its ability to absorb noise helps reduce the amount of unnecessary noise that might otherwise enter or leave a specific area. As such, it can be used to help reduce noise levels in a variety of busy areas, such as construction sites or industrial complexes.

In terms of working principle, 3M AB5020HF 1.5”CIRCLE-25 works by capturing and absorbing the energy of electromagnetic waves and ionized particles. This happens due to its closed cellular structure, which acts as a barrier to the passing of these forms of energy. The material is also able to contain and divert energy that is generated by internal sources, such as computer components and motors, helping to prevent their interference with external sources. By using this shielding material, the resulting level of radio frequency and electromagnetic radiation is greatly reduced.

In conclusion, 3M AB5020HF 1.5”CIRCLE-25 is a shielding and absorbing material used for a variety of RFI and EMI noise reduction solutions. It is made of a cellular polypropylene foam with superior protective properties against these forms of noise, such as corrosion resistance, flame retardance, and excellent shielding properties for effective EMI/RFI protection and attenuation. The material is also suitable for use in RF shielding enclosures and high-temperature and high-humidity environments. Its working principle is based on its closed cellular structure which effectively absorbs and redirects incoming electromagnetic waves and ionized particles.
