Radio Frequency Interference (RFI) and Electromagnetic Interference (EMI) negatively affects the performance of electronics, industries, and communication systems. RFI and EMI shielding and absorbing materials, such as CN-4490, are critical components to maintain stable and reliable electronic systems. In this article, we discuss the application field and working principle of the CN-4490.

CN-4490 is a metal-coated fabric that efficiently eliminates and absorbs RFI and EMI. It is made of nickel-coated polyester fabric-backed with a conductive acrylic pressure-sensitive adhesive. Its EMI shielding effectiveness and fire-retardant properties make it an ideal solution for shielding enclosure designs.

CN-4490 has a wide range of applications in various industries, such as the aerospace, automotive, telecommunications, medical, and defense industries. It is also suitable for applications where environmental or functional robustness is required, such as on ships and planes. It is also an excellent solution for containing and shielding magnetic emf from antennas, microphones, and other RF sources.

How does CN-4490 work? When the metal-coated fabric is applied, it forms an effective barrier for RFI and EMI. It does this by reflecting or absorbing the electromagnetic radiation. It absorbs the radiation by converting the energy into thermal energy, which is then dissipated into the environment.

CN-4490 is also fire-resistant and does not give off toxic fumes or gases when exposed to high temperatures. The metal-coated fabric has a flame-resistant liner made of non-halogen, non-toxic material, meaning it is safe for use in all types of environments.

CN-4490 is also effective in reducing noise and is capable of reducing noise levels by up to 50dB. It provides excellent environmental sealing that will not degrade over time. It is also heat-resistance up to 500 degrees Celsius and can be applied directly onto the surface of a printed circuit board or other electronic component.

CN-4490 has excellent adhesive properties, making it easy to install and remove. It is suitable for both indoor and outdoor environments, making it a cost-effective solution for applications where both shielding and sealing are required. It is also an excellent solution for applications where weight and space limitations are a factor.

The CN-4490 metal-coated fabric is one of the most effective solutions for reducing RFI and EMI, as well as providing fire-resistant properties. Its wide range of applications and cost-effectiveness make it an ideal shielding and sealing solution for industries looking for reliable and robust protection.
