RFI & EMI (Radio Frequency Interference and Electromagnetic Interference) shielding and absorbing materials are designed to reduce or block the electromagnetic radiation created in a variety of environments. 3M CN3490 8” x 10.5”-25 is a type of shielding and absorbing material with specific features and benefits that can help reduce or block RFI and EMI.

The product has a thin polyester film with 2-mil nickel-copper shielding layer. The combination of the film layer and the shielding layer provide reliable performance and reliability even in severe environmental conditions. The product is easy to install, and the high-performance adhesive backing ensures long-lasting durability. The product has a high temperature adhesive, so it can be used in both indoor and outdoor situations.

3M CN3490 8” x 10.5”-25 has excellent performance in both RFI and EMI situations. It provides a very high level of shielding effectiveness over a wide frequency range, including 70 KHz up to 6 GHz. This means that it can effectively reduce interference from most standard radio frequencies, which is especially important in applications that may be subject to high levels of EMI or RFI. In addition, the product can be combined with other types of insulation materials for even higher levels of shielding protection.

Another major benefit of 3M CN3490 8” x 10.5”-25 is that it has excellent performance in high temperature applications. This is due to the high temperature adhesive backing, which enables it to remain secure even in harsh conditions. As a result, it is ideal for areas that may be exposed to extreme temperatures, such as automotive, appliance, or military applications.

One of the most important applications for this type of shielding and absorbing material is automotive interior noise control. This is because it can help reduce the amount of noise created inside the vehicle, by blocking as much as 70% of high frequency noise. This is particularly useful for vehicles that are subject to a lot of road noise, as reducing the amount of noise coming into the cabin can help make for a more comfortable ride. Furthermore, 3M CN3490 8” x 10.5”-25 can also be used to help reduce the amount of noise that is emitted in other areas, such as the engine bay.

Another critical application for 3M CN3490 8” x 10.5”-25 is in the aerospace industry. This is because the product’s shielding and absorption performance can help protect sensitive electronics from damage due to the high levels of radiation and EMI experienced in flight. This type of protection is especially important on aircraft as the combination of high temperatures and strong electrical interference can quickly cause significant damage to sensitive components.

Finally, some electronic device manufacturers also employ 3M CN3490 8” x 10.5”-25 for the purpose of improving the quality of their products. Because the product is easy to install and has excellent shielding and absorption performance, manufacturers can reduce interference from both internal and external electronic components. This can enable their products to produce clearer audio or video signals, which can ultimately lead to a higher quality product that meets more stringent criteria.

In conclusion, 3M CN3490 8” x 10.5”-25 is a reliable and durable shielding and absorption material made from a thin polyester film with a 2-mil nickel-copper layer. Its combination of shielding and absorption performance makes it ideal for a variety of applications in both the automotive and aerospace industries, as well as for manufacturers of electronic devices. In addition, its easy installation and high temperature adhesive backing make it well suited for both indoor and outdoor applications. This type of shielding and absorption material can help reduce or block RFI and EMI in a variety of scenarios, helping to ensure a more comfortable and safe environment for its users.
