The advent of electricity in the industrial and consumer worlds has created a need for shielding and absorbing materials to protect electronic equipment from interference, such as radio-frequency interference (RFI) and electromagnetic interference (EMI). 3M 1170 CIRCLE-1"-250 is one such material. This material is primarily designed to provide shielding for electronic applications and reduce the risk of RFI and/or EMI issues, as well as providing thermal management applications.

This shielding and absorbing material is composed of a flexible film from highly conductive aluminum coated with an acrylic adhesive. It is designed in the shape of an X-ring which provides flexibility and easy application. It also provides corrosion and chemical resistance, as well as excellent flexibility and electrical conductivity.

The application field for this shielding and absorbing material includes audio-visual displays, consumer electronics, industrial and automation control electronics, telecommunications, and medical devices. Additionally, it can be used in antenna coatings, printed circuit boards and cable repairs.

3M 1170 CIRCLE-1"-250 provides maximum shielding and absorption by reflecting and containing the electromagnetic signals and radio waves generated by an electronic device, and also provides additional protection against RFI and EMI. It works by creating an “electromagnetic barrier” which blocks the interference from entering or leaving the device.

The working principle of this shielding and absorbing material is based on the idea that the aluminum film acts as a conductor to create an electromagnetic field that surrounds the device and blocks any interference. This material is designed to resist the ingress of noise generated by other signals from the outside environment, and also prevents any signals from the device from interfering with other devices.

3M 1170 CIRCLE-1"-250 is an excellent example of a shielding and absorbing material, providing protection from RFI and EMI. This material is designed to be flexible and easy to apply, and is suitable for a variety of applications. Additionally, it provides maximum shielding and absorption of electromagnetic signals, providing additional protection against interference.
