RFIs and EMIs, also known as radio frequency interference and electromagnetic interference, are forms of energy which can cause disruption of electronic equipment. These forms of energy can come from a variety of sources, including power lines, cell phones, and digital television transmitters. In order to reduce or even eliminate the impact of this interference on electronic equipment, shielding and absorbing materials are employed.21445100 is a type of shielding and absorbing material. It is a three layer construction consisting of a high performance aluminum-zinc alloy foil, polyester film, and a electro-statically conductive pressure-sensitive adhesive. Additionally, the material is UL recognized, meaning it meets basic safety standards.The primary application of this type of material is as an electromagnetic shield for enclosures and connectors. By creating a Faraday cage, or an enclosure made of a conducting material, the material acts as a barrier between the interfering electromagnetic field and the equipment inside the enclosure. This creates a controlled environment in which the equipment can work without being affected by an interfering field.In addition to shielding against RFI and EMI, 21445100 has other applications. It can be used to eliminate static electricity, such as in computer and data storage rooms, and can be used for heat dissipation. Additionally, it can be used in the automotive industry for applications such as shielding in engine compartments.In terms of working principle, the material creates a Faraday cage which prevents the transfer of interference from the external environment to the protected enclosure. The aluminum-zinc alloy foil acts as the conductor, while the pressure sensitive adhesive ensures that the material is securely in place. The polyester film helps to ensure that there are no gaps in the cage, further preventing the transfer of interference.In conclusion, 21445100 is an effective shielding and absorbing material that can be used to protect electronic equipment from RFI and EMI. It creates a Faraday cage to prevent the transfer of interference, and has applications in a variety of industries, from electronics to automobiles. In addition to shielding, this type of material can be used for other purposes such as static electricity elimination and heat dissipation.
