Radio Frequency Interference (RFI) and Electromagnetic Interference (EMI) have become an increasingly significant problem in many environments. Shielding and absorbing materials are an essential component of any intervention to minimise these problems with the most common techniques being the application of a metal wall or Faraday cage. 7882018 is a polymer material developed that offers a unique combination of attributes to provide excellent RFI and EMI shielding. This article looks at the development of the material, provides an overview of the core application fields and presents the underlying working principle.7882018 is a two-component material offering enhanced performance due to the special micro-structure of the polyurethane/polypropylene blend. Its core features include excellent RFI and EMI shielding performance, suitability for use in harsh industrial environments, excellent durability and resistance to physical and chemical wear, and very good acoustic filling effect. Its combination of properties make it an ideal choice when shielding objects or devices from electromagnetic radiations and disruptions.The applications for 7882018 polymer are wide and varied and the material has been successfully implemented in an array of industries and application areas. Of particular note, in the automotive and defence industries, the material has been used to provide shielding for electronic components and systems. In the medical and aerospace industries the material has been employed in the production of medical diagnostic and instrumentation equipment. Finally, the material is also used for shielding of wireless communications systems.The working principle of 7882018 is based on two fundamental principles. Firstly, it acts as an effective barrier to electromagnetic interference due to the special micro-structure of the polymer, which is able to close the gaps in a regular shielding metal mesh. Secondly, the material is able to absorb some of the electromagnetic energy due to its dielectric properties. In this way the material is able to attenuate the incoming electromagnetic signal and reduce the possibility of interference.In conclusion, 7882018 is a two-component polymer material specifically designed to provide enhanced RFI and EMI shielding performance with excellent compatibility across a variety of industrial and data communications applications. The material has a micro-structure which is able to close the gaps in a regular shielding mesh and also has dielectric properties which provide additional attenuation of the incoming electromagnetic signal. The combination of these attributes provides excellent shielding performance and compatibility across a wide range of applications.
